Abstract:
1. A system comprising: a light modulation unit configured to produce a modulated light stream by modulating an incident stream of light with a sequence of spatial patterns; a light sensing device configured to generate an electrical signal that represents intensity of the modulated light stream as a function of time, wherein the light sensing device is further configured to generate a sequence of samples of the electrical signal; an electronic subsystem configured to apply a filter to the electrical signal in order to obtain a filtered signal, wherein the filter is configured to attenuate one or more noise components present in the electrical signal, wherein a set of samples of the filtered signal, corresponding to M of the spatial patterns, is usable to construct an n-pixel image or n-voxel video sequence, wherein M and n are positive integers, wherein M is less than n, wherein the electronic subsystem is configured to:
