Re: Periscop

At least one of the iPhone models that's coming in 2023 will feature a "periscope" lens, according to information shared by Apple analyst Ming-Chi Kuo, who often provides accurate insight into Apple's plans.
First and foremost, Kuo has had little to say about the feature set that might be included when Apple adopts periscope lens technology. Due to the lack of information, we have no idea at this time what Apple's periscope lens might be capable of, aside from an increase in optical zoom capabilities. Other sources have confirmed that Apple is working on periscope lens technology, but no concrete details have emerged.
It's not clear how Apple plans to implement a periscope lens, but in general, the technology uses a prism or mirror to refract light onto the lens sensor for magnification purposes, with the mechanics of the lens built into the inside of the smartphone instead of the outside like a traditional zoom lens for a DSLR.

Periscope lens technology has advanced enough that in smartphones, the lenses are compact and small enough to fit into a normal lens enclosure and don't even take up too much internal space. Depending on the build of the phone and internal space available, a periscope lens could theoretically be quite long, allowing for impressive levels of optical zoom.
The iPhone 14 Pro models offer 0.5x zoom (ultra wide-angle lens) and 1x zoom (wide-angle lens) alongside the 3x telephoto lens. With a periscope lens, Apple would presumably bump up the telephoto lens capabilities to allow it to zoom in further than 3x.
The periscope lens would likely be limited to the telephoto camera, as this technology works best in a single lens situation. So you'd have a single camera that can zoom in super far alongside other more standard wide-angle and ultra wide-angle cameras.
Periscope-style lenses for advanced optical zooming capabilities are trending right now, and several manufacturers have implemented the technology. Apple's main competitor, Samsung, has introduced several Galaxy Ultra devices with with hybrid 10x optical zoom capabilities.
Huawei has come out with the P30 Pro, which also offers 5x true optical zoom and 10x hybrid optical zoom, and the company is rumored to be working on a P40 Pro that has even more advanced true 10x optical zoom capabilities..

Samsung calls the zoom functionality in its smartphones "Space Zoom" and it enables up to 100x digital zoom. The periscope lens itself uses a folded 4x telephoto lens combined with a 48-megapixel sensor, which can swap between 4x and 10x zoom. Samsung's zoom feature is technically a hybrid option because it uses some sensor cropping for the 10x zoom.
The 100x zoom capability uses digital zooming technology that we thought worked quite well up to 30x, but is not particularly useful at 100x. Apple, like Samsung, could combine digital zoom with optical zoom for a similar effect.
So far, periscope zoom lenses in smartphones that are truly 10x are available in limited quantities, but the technology is certainly on the verge of expanding and should be even more advanced by the time Apple is ready to build it into a smartphone in 2023.
According to the description included in the patent, light would be channeled into the camera through a primary lens, bounced off of the included mirror in the smartphone, and then would be sent to a secondary lens that moves up and down for the purpose of zooming in.

Periscopul este un instrument optic alcătuit din lentile, oglinzi, și/sau prisme cu ajutorul căruia se pot efectua observații ntre două niveluri diferite ca nălțime (tranșee, dintr-un submarin etc).
n domeniul naval, periscopul este folosit de submarine pentru a da posibilitatea acestora să supravegheze situația de la suprafața apei, fără a fi văzut.
De regulă, tubul periscopului de pe submarine este telescopic și este prevăzut cu dispozitiv de ridicare sau coborre ce permite nălțarea sa și retragerea pe timpul deplasării, rotire n plan orizontal sau de rotire pe verticală a obiectivului.
Sistemele optice ale unui periscop permit măsurători de distanțe și unghiuri, pentru stabilirea elementelor de atac cu torpile.
Tipuri de periscose bazeaza pe un număr ct mai mare de instrumente și aparate care să satisfacă necesitățile practice date. Aceste instrumente și aparate sunt alcătuite din componente optice, care, n raport cu tipul respectiv, ndeplinesc anumite funcții bine determinate.
