Multi-plane unequal interval imaging based on polarization multi...

We propose an approach for imaging multi-plane-object where the image contents at different distant planes are recorded simultaneously in a single shot. The method is based on a compound quadratic distorted (QD) grating and the polarization multiplexing technique. The compound grating consists of two QD gratings with different parameters, which controls the distance interval between object planes. In polarization multiplexing technique, the images on x- and y- directions are modulated into ortho
