Abstract

An optical sensor device may comprise an optical sensor comprising a set of sensor elements; an optical filter comprising one or more channels, wherein each channel, of the one or more channels, is configured to pass light associated with particular wavelengths to a subset of sensor elements, of the set of sensor elements, of the optical sensor; a phase mask configured to distribute a plurality of light beams associated with a subject in an encoded pattern on an input surface of the optical filter; and one or more processors. The one or more processors may be configured to obtain, from the optical sensor, sensor data associated with the subject and determine, based on the sensor data, spectral information associated with the subject. The one or more processors may determine, based on the sensor data and information associated with the encoded pattern, spatial information associated with the subject.
