Claim Text:
1. A system comprising: a spectral separation subsystem configured to receive a modulated light stream, wherein the modulated light stream is generated by modulating an incident light stream with a temporal sequence of spatial patterns, wherein the incident light stream carries images from an external environment, wherein the spatial patterns belong to a set of measurement vectors that is incoherent with a second set of vectors in which the images are sparse, wherein the spectral separation subsystem is configured to separate the modulated light stream into a plurality of wavelength components; an array of light sensing elements, wherein the light sensing elements are configured to receive respective subsets of the wavelength components and to generate respective electrical signals, wherein each of the electrical signals represents intensity of the respective subset of the wavelength components as a function of time; a sampling subsystem configured to sample the electrical signals in order to obtain respective sample sequences; a detection unit configured to monitor a selected subset of the electrical signals to detect an event occurring within a field of view corresponding to the incident light stream, wherein said detecting the event includes determining when the selected subset of electrical signals satisfy a pre-determined signal condition; a processing unit configured to reconstruct a temporal sequence of images based on the sample sequences; a display device configured to the display the temporal sequence of images to a user; wherein the processing unit is configured to:
