System and method for compressed sensing light field camera

A light-field imaging system, comprising:

• a detector having a pixel matrix;
• an optical arrangement configured for collecting an input light field from a scene and projecting collected light on the pixel matrix,
• wherein the optical arrangement
• separating the collected light into u angular light components corresponding to u different discrete viewpoints of the scene and project light from the u angular light components onto each of a plurality of pixel regions of the pixel matrix;
• wherein all the u angular light components are collected by the detector on each of the plurality of pixel regions;
• and
• a color filter:
• located in a filtering plane in an optical path of the u angular light components of the collected light,
• having a plurality of filter elements including a plurality of transparent filter elements and a plurality of filter elements of at least two wavelength bands selected from a group comprising:
• red wavelength, green wavelength, blue wavelength, cyan wavelength, magenta wavelength, and yellow wavelength;
• and
• configured to filter the light propagating to the pixel matrix, thereby forming on the pixel matrix an image of the input light field in a spectro-angular space;
• wherein the plurality of transparent filter elements are transparent to visible spectrum and distributed in the in filtering plane such that a probability of one of the plurality of color filters to be a transparent filter element is at least about −40 percent.
