This invention is a reference-free snapshot wavefront camera that can be used to measure both amplitude and phase of the wavefront. The camera uses a two-dimensional diffraction grating to split the incoming wavefront into multiple copies which then travel through a lens that focuses them onto a sensor in a camera array. The resulting wavefront information...

Dispersive Element as a Wavelength Recombiner for AVHF

This invention is a technique to compensate for the spectral dispersion of the Advanced Volume Holographic Filter (AVHF) using yet another dispersive element. This new element acts as a spectral recombiner and collimate all the different wavelengths. Background: The Advanced Volume Holographic Filter (AVHF) is a holographic system capable of broadband...
