Abstract

An apparatus for compressive sensing may include a filter array, a detector, and a reconstruction engine. The filter array may be configured to generate a first illumination pattern in response to a first wavelength of light and a second illumination pattern in response to a second wavelength of light. The first illumination pattern and the second illumination pattern may be projected onto an object. The detector may be configured to determine a first intensity of a first light emitted by the object in response to the first illumination pattern and a second intensity of a second light emitted by the object in response to the second illumination pattern. The reconstruction engine may be configured to generate an image of the object based at least on the first intensity, the first illumination pattern, the second intensity, and the second illumination pattern.
