Lensless Imaging with Focusing Sparse URA Masks in Long-Wave Infrared and its Application for Human Detection
We introduce a lensless imaging framework for contemporary computer vision applications in long-wavelength infrared (LWIR).
Programmable Spectral Filter Arrays using Phase Spatial Light Modulator
Spatially varying spectral modulation can be implemented using a liquid crystal spatial light modulator (SLM) since it provides an array of liquid crystal cells, each of which can be purposed to act as a programmable spectral filter array.
Spatial Phase-Sweep: Increasing temporal resolution of transient imaging using a light source array
Transient imaging or light-in-flight techniques capture the propagation of an ultra-short pulse of light through a scene, which in effect captures the optical impulse response of the scene.
Depth Selective Camera: A Direct, On-Chip, Programmable Technique for Depth Selectivity in Photography
Time of flight (ToF) cameras use a temporally modulated light source and measure correlation between the reflected light and a sensor modulation pattern, in order to infer scene depth.
