MetaTele: Compact Refractive Metasurface Computational Telephoto Camera
Harshana Weligampola, Yuanrui Chen, Abhiram Gnanasambandam +4
Smartphone cameras face fundamental form-factor constraints that limit their optical magnification, primarily due to the difficulty of reducing a lens assembly's telephoto ratio, t…
Fast PSF Synthesis with Defocused and Spherical Aberration
Nicholas Ganino, Qi Guo
Accurately estimating the point spread function (PSF) of an optical system requires solving free-space wave propagation, which entails evaluating a diffraction integral. This integ…
SpiderCam: Low-Power Snapshot Depth from Differential Defocus
Marcos A. Ferreira, Tianao Li, John Mamish +4
We introduce SpiderCam, an FPGA-based snapshot depth-from-defocus camera which produces 480x400 sparse depth maps in real-time at 32.5 FPS over a working range of 52 cm while consu…
