SASSI — Super-Pixelated Adaptive Spatio-Spectral Imaging

SASSI Video-rate Hypterspectral Imager We introduce a novel video-rate hyperspectral imager with high spatial, temporal and spectral resolutions. Our key hypothesis is that spectral profiles of pixels within each super-pixel tend to be similar. Hence, a scene-adaptive...

Reference Wave Design for Wavefront Sensing

ReWave phase-shifting point diffraction interferometry One of the classical results in wavefront sensing is phase-shifting point diffraction interferometry (PS-PDI), where the phase of a wavefront is measured by interfering it with a planar reference created from the...
