Image science investigates the ways that image quality can be defined, measured and optimized; it touches and improves the visualization of everything from healthy bones to unstable atmospheres to millennia-old geological formations. This interdisciplinary field studies the physics of photon generation, the propagation of light through optical systems, signal generation in detectors and more, and considers the statistics of random processes and how they affect the information contained within images.
The faculty in image science at the Wyant College of Optical Sciences show particular strength in designing new technology for medical imaging, homeland security, earth sciences and other applications, and in developing new methods for assessing image quality by quantifying how accurately imaging systems can accomplish certain analytical tasks.
Three Wyant College of Optical Sciences PhD students, all advised by Travis Sawyer, Assistant Professor of Optical Sciences, have had their research featured on prominent journals' covers. Justina Bonaventura is first author of the article, "Evaluating backscattering polarized light imaging microstructural mapping capabilities through neural tissue and analogous phantom imaging," published in the May 2024 issue of SPIE's peer-reviewed Journal of Biomedical Optics. Noelle Daigle and Shuyuan Guan; with advisor, Travis Sawyer; co-authored the article, "Two-Photon Microscopy Provides Clear Guidance for Tumor Resection," featured in the May/June 2024 issue of BioPhotonics, a news journal published by Photonics Spectra.
Professor David Brady's work in computational imaging attracted the attention of writers at SPIE who focused an article on the work he is doing to build a camera capable of creating the world's first gigapixel images. The machine contains an array of 98 microcameras with microprocessors that can stitch the individual images together. According to the article, "Computational imaging, on the other hand, allows users to refocus a photo, construct a 3D picture, combine wavelengths, or stitch together separate images into one.
Using a slip aperature and diffraction grating on a smartphone, the research team, including Dongkyun "DK" Kang, has developed a confocal microscope. It's use for in vivo human skin imaging was successful, conducting two-dimensional confocal imaging without the need for any beam scanning devices. These results suggest that the smartphone confocal microscope has a potential to be a low-cost option capable of examining cellular details in vivo and may help disease diagnosis in resource-poor settings, where conducting standard histopathological analysis is challenging.
ISA provides image quality targets, software, and consulting to the digital image archiving community. Our products enable quality control for the digitization of both transmissive and reflective material from books to historic maps to artwork, baseball cards and more.
Imaging science is the study of the science, computing, and engineering theories behind the technology that goes into creating images, the integration of this technology into imaging systems, and the application of those systems to gather information and solve scientific problems. Imaging science is used to design and develop cutting-edge imaging systems, such as portable eye trackers, virtual reality devices, satellite systems, digital cameras, or anything that involves recording, processing, displaying, or analyzing image data.
Co-ops and internships take your knowledge and turn it into know-how. Science co-ops include a range of hands-on experiences, from co-ops and internships and work in labs to undergraduate research and clinical experience in health care settings. These opportunities provide the hands-on experience that enables you to apply your scientific, math, and health care knowledge in professional settings while you make valuable connections between classwork and real-world applications.
The Office of Career Services and Cooperative Education offers National Labs and federally-funded Research Centers from all research areas and sponsoring agencies a variety of options to connect with and recruit students. Students connect with employer partners to gather information on their laboratories and explore co-op, internship, research, and full-time opportunities. These national labs focus on scientific discovery, clean energy development, national security, technology advancements, and more. Recruiting events include our university-wide Fall Career Fair, on-campus and virtual interviews, information sessions, 1:1 networking with lab representatives, and a National Labs Resume Book available to all labs.

Faculty working on cultural heritage imaging develop novel imaging systems and algorithms to analyze historical artifacts around the world. Research is primarily focused on multi- and hyperspectral imaging, but also includes imaging modalities such as reflectance transformation imaging and X-ray fluorescence. An active area of research is also the development of novel 3D visualization tools for scholars to interact with the digital artifacts after image collection and processing.
Research in this area focuses on the development of novel imaging systems, primarily for astronomical applications. Significant research has been conducted on the use of Digital Micro-mirror Devices in multi-object spectrometers for astronomical imaging systems. Additional work has focused on random apertures for extremely large space-based telescopes and vortex coronagraph imaging systems. Additional work in optical systems includes research into the use of ultrafast lasers for the development of novel photonic detectors and other surface polishing applications.
The Multidisciplinary Vision Research Laboratory combines expertise in eye tracking instrumentation, cognitive science knowledge of the human visual system, and computer vision to understand how the eye-brain system works, as well as how to leverage that knowledge into novel computer vision systems.
