Abstract: An imaging system includes multiple diffractive optical gratings disposed over a two-dimensional array of photosensitive pixels. The different gratings present different patterns and features that are tailored to produce point-spread responses that emphasize different properties of an imaged scene. The different responses are captured by the pixels, and data captured from the responses can be used separately or together to analyze aspects of the scene. The imaging systems can include circuitry to analyze the image data, and to support modes that select between point-spread responses, selections of the pixels, and algorithms for analyzing image data.

Abstract: An imaging system with a diffractive optic captures an interference pattern responsive to light from an imaged scene to represent the scene in a spatial-frequency domain. The sampled frequency-domain image data has properties that are determined by the point-spread function of the diffractive optic and characteristics of the scene. An integrated processor can analyze the characteristics of captured image data and select one of multiple available reconstruction kernels for transforming the frequency-domain image data into a spatial-domain image of the scene.
