Abstract:
1. A method for capturing images of a scene using an imaging system, the method comprising: identifying a plurality of spatially aperiodic patterns; illuminating the scene with the plurality of spatially aperiodic patterns using an illumination system; identifying a plurality of spatially periodic patterns reflected from the illuminated scene, wherein the plurality of spatially aperiodic patterns are configured to produce the plurality of spatially periodic patterns when reflected from the illuminated scene from the perspective of the imaging system; identifying at least one image of the scene, the at least one image having a plurality of modulated components based on modulating the scene with the spatially periodic pattern; identifying at least one modulation frequency for the at least one captured image; using the identified modulation frequency to demodulate the modulated components of the at least one image; and storing the at least one demodulated image.
