Original Abstract Submitted
a three-dimensional (3d) compressive sensing based eye tracking system using single photon avalanche diode (spad) sensors achieves high resolution depth measurement by using low resolution spad sensors and active encoded illumination such as two- or three-dimensional fringe patterns, random speckles, random patterns, and/or superimposed patterns projected onto a surface of an eye. the patterns may be projected by high speed illuminators such as a digital micromirror device (dmd) or micro-electromechanical system (mems) projector in series changing at the same rate as the spad sensor capture rate. a processor may employ compressive sensing techniques to obtain a high resolution image and depth information from the captured images of varying patterns.
