Reflector 1.2.3
Harriet Wehrenberg
Reflector ships with a reflector.service. The service will run reflector with the parameters specified in /etc/xdg/reflector/reflector.conf. The default options in this file should serve as a good starting point and example.
pacman-mirrorlist is not updated regularly, invoking reflector only because some mirror in some part of the globe was added or removed is not relevant. Use instead the timer-based automation. If you do not want mirrorlist.pacnew to be installed at all, use NoExtract in pacman.conf.
Made with premium fabrics with durable steel-riveted frames, these square and rectangular shaped reflectors offer a larger surface area than round reflectors. You'll shoot with confidence knowing these reflectors are backed by a lifetime limited warranty.
I just got 6 new 800w Strobes and was not looking foreword to having to carry around bulky inconvenient modifiers when I set up for sporting events. Thank goodness for MagMod Reflector XL! I picked up 2 of the cases and they store all 6 of the reflectors. Looking forward to trying them out at a large event soon and the ease of adjusting their angle of coverage if required.
- The RECCO Backpack rescue reflector has been specially designed for the application on carrying straps of backpacks and is primarily intended for use in summer to be located by helicopter if gone missing.
- NOTE: When using the backpack rescue reflector in zones with avalanche danger in winter, it is important that the reflector is only used on backpacks that are secured like an avalanche airbag backpack with a leg loop, since a detached backpack with a reflector in an avalanche can lead to a false signal.
The slightly textured open reflectors are characterised by homogenous light distribution, although a controlled centre emphasis can be achieved using focusable broncolor lamps. The light angle of each open reflector is apparent from its model designation, optical attachments (such as projection attachment) offer a variable coverage angle.
It is just that! It reflects light. There are hundreds of different types of reflectors, which differ in sizes and colors (i.e. white, silver, gold, etc.). A reflector is usually a reflective fabric, stretched over a bendy ring, allowing it to fold, and easy to carry.
I sometimes use other larger reflectors (mainly in cinematography productions), but this 12 inch reflector suits my needs in travel photography; mainly because it is small enough, allowing me to hold it with one hand and the camera with the other.
The above picture was taken on the border of Afghanistan and Tajikistan. Please note that although the woman is standing in the shade and the background is bright, the woman is not a black silhouette and the background is not burned out. I measured the light from the background (using spot metering). In such a situation, without using a reflector, the character will turn out completely black (silhouette) but with a reflector held on my left hand, I was able to light up her face.
It is important to keep in mind that the closer the light source is to the photographed subject, the stronger and less soften it will appear. Thus, a small reflector is easier to carry and hold; however it will be not as soft as a large reflector.
One of the most useful techniques, in order learn how to work with natural light in my opinion, is by observing the images of other photographers. Try to guess the direction of the light and the position and color of the reflector in the images below:
Built with high-quality materials and fabrics, it allows for heavy-duty use during long studio hours. The Soft Zoom Reflector comes with a custom-made carrying case that fits the reflector and zoom rod, ensuring that it's always protected and ready to use.
The beryllium reflector helps drive neutron production by reflecting stray neutrons back into the core as they are generated. After more than 20 years of successful operation, the reflector is approaching the end of its lifetime and will need to be replaced.
The Polaris Series telescopes come in a variety of apertures including 90mm refractor and 114mm reflector. These telescopes deliver bright and clear images with the greatest detail and enables observation of the craters of the Moon, Saturn's rings, and even Jupiter's surface. Meade's Polaris telescopes are perfect for the astronomer who wishes to manually observe and discover the night sky with ease.
After the Ridgecrest M7.1 earthquake on July 6, 2019, the coordinates were adjusted for a one time 1.25 CMS North displacement and with new rates for the North component:
- delta_east_in_meters = -0.023491 * ( gps_time_past_6-jul-2019_in_secs) / 365.25 / 86400
- delta_north_in_meters = 0.008048 * ( gps_time_past_6-jul-2019_in_secs) / 365.25 / 86400
- delta_vertical_in_meters = -0.000670 * ( gps_time_past_6-jul-2019_in_secs) / 365.25 / 86400
L-band image of 350 heading corner reflectors Accuracy & History As of November 4, 2015, the location of the bottom vertex of CRs #04 through #12 and CRs #15 through #27 have been surveyed to an accuracy of 2 cm RMS. Several CRs on the west end of the array, specifically CRs #00, #01, #02, #03, #13, and #14 have yet to be surveyed to this accuracy and are believed to be known to around 10 cm RMS.
Use the 'Get Corner Reflector Data' button to retrieve the vertices of the the Rosamond corner reflectors (latitude, longitude, orientation, etc) for a particular date. Data goes back to January 1, 2000. Output is a comma-separated value (CSV) file.
Although perfect for beginning stargazers, this tabletop reflector telescope is not a toy! With its substantial, 100mm aperture parabolic primary mirror boasting a 400mm focal length, the compact Orion SkyScanner 100mm TableTop Reflector telescope will amaze you and your family with gorgeous, detailed views of the night sky.
With this capable reflector, you can study the Moon's cratered surface in detail, exploring highland mountains and vast, planar lunar "seas" of dark material. Bright planets like Jupiter, Saturn, and Mars shine bright in the SkyScanner 100mm Reflector, even when viewing from urban locations with mediocre seeing conditions. On especially clear evenings when viewing from areas with dark skies, the pint-sized Orion SkyScanner telescope can gather enough light for views of open and globular star clusters, bright cloudy nebulas, and even a few distant galaxies.
NOTE: The SkyScanner is a reflector type telescope, and reflectors are not recommended for daytime terrestrial viewing because the image in the eyepiece is not right-side up. But reflector telescopes make great astronomical instruments, because there is no "right side up" in space!
An AstroMesh configuration is available for almost every off-set space antenna application, and with its best in class compaction ratios, AstroMesh can be stowed for the most challenging launch envelopes. Astro has developed a flight proven family of deployable mesh reflectors capable of excellent RF performance from low frequency (UHF) to high frequency (beyond Ka-Band) in aperture sizes ranging from 3 to 22 meters. Our designs are scalable, inherently stiff, incredibly light with unmatched surface accuracy, and free from the Passive Inter-Modulation (PIM) that plagues most competitive designs.
Amateur astronomer Andrew A. Common built the Crossley Reflector in Great Britain in 1879, around the time that the Great Lick Refractor was built. The Great Refractor was one of the last large refractors built, and the Crossley was one of the first large reflectors built. Large reflectors became practical after 1880, when a new technology for making concave, silver-coated glass mirrors was perfected. Prior to this, such mirrors required constant polishing to remain reflective.
With his reflector, A.A. Common was the first to discover that stars too faint to be seen through a telescope with the eye could be imaged in photographs taken through the telescope using a long exposure time. This discovery is the basis for all modern astrophotography and spectroscopy. For these early astronomical photographs, Common was awarded the Royal Astronomical Society gold medal for Astronomy.
After deciding to build a larger telescope, Common sold the 36-inch reflector to Edward Crossley in 1885. Crossley built a new dome enclosure to protect the telescope and observers from the harsh Halifax (UK) weather, but this climate was far from ideal for observation. After about 10 years, Crossley donated both telescope and dome to Lick Observatory, where it was put into operation in 1896.
The 36-inch Crossley reflector was used for observation extensively before the 120-inch Shane reflector was built on Mt. Hamilton in 1959. After this, the Crossley reflector was used occasionally for research until 2009, although it has limited light-gathering ability and is not physically easy to use. Research in the recent past includes SETI (Search for Extraterrestrial Intelligence) projects, eclipsing binary star research, and some extrasolar planetary search observations.
Wire-guided localisation (WGL) has been the mainstay for localising non-palpable breast lesions before excision. Due to its limitations, various wireless alternatives have been developed. In this prospective study, we evaluate the role of radiation-free wireless localisation using the SAVI SCOUT system at the London Breast Institute. A total of 72 reflectors were deployed in 67 consecutive patients undergoing breast conserving surgery for non-palpable breast lesions. The mean interval between deployment and surgery for the therapeutic cases was 18.8 days (range: 0-210). The median deployment duration was 5 min (range: 1-15 min). The mean distance from the lesion was 1.1 mm (median distance: 0; range: 0-20 mm). The rate of surgical localisation and retrieval of the reflector was 98.6% and 100%, respectively. The median operating time was 28 min (range: 15-55 min) for the therapeutic excision of malignancy and 17 min (range: 15-24) for diagnostic excision. The incidence of reflector migration was 0%. Radial margin positivity in malignant cases was 7%. The median weight for malignant lesions was 19.6 g (range: 3.5-70 g). Radiologists and surgeons rated the system higher than WGL (93.7% and 98.6%, respectively; 60/64 and 70/71). The patient mean satisfaction score was 9.7/10 (n = 47, median = 10; range: 7-10). One instance of signal failure was reported. In patients who had breast MRI after the deployment of the reflector, the MRI void signal was
