  • Free orientation fourier camera
    Patent number: 11468557
    Abstract: Certain aspects pertain to Fourier camera systems and methods. In one aspect, a Fourier camera comprises a first optical system, a second optical system, a variable aperture filter, and a light detector. The first optical system configured to receive illumination reflected from a curved sample surface. The variable aperture filter configured to move an aperture to a plurality of aperture locations in a Fourier plane, wherein the aperture filters light from the first optical system to the second optical system. The light detector configured to receive light from the second optical system, and configured to acquire a plurality of raw intensity images of the curved sample surface corresponding to the plurality of aperture locations, wherein the raw images are iteratively updated in overlapping regions in Fourier space to generate a focused, substantially uniform resolution image of the curved sample surface, and wherein the overlapping regions correspond to the plurality of aperture locations.
