Abstract: A wavefront sensor includes a mask and a sensor utilized to capture a diffraction pattern generated by light incident to the mask. A reference image is captured in response to a plane wavefront incident on the mask, and another measurement image is captured in response to a distorted wavefront incident on the mask. The distorted wavefront is reconstructed based on differences between the reference image and the measurement image.

Abstract: The microlens amplitude masks for flying pixel removal in time-of-flight imaging includes systems, devices, methods, and instructions for image depth determination, including receiving an image, adding noise to the image, determining a set of correlation images, each correlation image having a varying phase offset, for each pixel of the image, generating a masked pixel by applying a mask array, and for each masked pixel, determining the depth of the masked pixel to generate a depth map for the image on a per pixel basis.
