Deep learning for camera data acquisition, control, and image estimation

DJ Brady, L Fang, Z Ma - Advances in Optics and Photonics, 2020 - opg.optica.org
We review the impact of deep-learning technologies on camera architecture. The function of
a camera is first to capture visual information and second to form an image. Conventionally …

Parallel cameras

DJ Brady, W Pang, H Li, Z Ma, Y Tao, X Cao - Optica, 2018 - opg.optica.org
Parallel lens systems and parallel image signal processing enable cost efficient and
compact cameras to capture gigapixel scale images. This paper reviews the context of such …

computational photography. Conventional methods either sacrifice resolution, use multiple …

Pseudorandom phase masks for superresolution imaging from subpixel shifting

A Ashok, MA Neifeld - Applied optics, 2007 - opg.optica.org
We present a method for overcoming the pixel-limited resolution of digital imagers. Our
method combines optical point-spread function engineering with subpixel image shifting. We …

Array camera image fusion using physics-aware transformers

Q Huang, M Hu, DJ Brady - arXiv preprint arXiv:2207.02250, 2022 - arxiv.org
We demonstrate a physics-aware transformer for feature-based data fusion from cameras

Demonstration of image-zooming capability for diffractive axicons

G Druart, J Taboury, N Guérineau, R Haïdar, H Sauer… - Optics letters, 2008 - opg.optica.org
Diffractive axicons are optical components producing achromatic nondiffracting beams. They
thus produce a focal line rather than a focal point for classical lenses. This gives the …
