Abstract
Image-sensing devices include odd-symmetry gratings that cast interference patterns over a photodetector array. Grating features offer considerable insensitivity to the wavelength of incident light, and also to the manufactured distance between the grating and the photodetector array. Photographs and other image information can be extracted from interference patterns captured by the photodetector array. Efficient extraction algorithms based on Fourier deconvolution introduce barrel distortion, which can be removed by resampling using correction functions. The sensing devices can be made to minimize distortion that results from efficient extraction algorithms based on Fourier deconvolution.
