ABSTRACT:
An true time delay in optical signals using a Fourier cell is provided. One embodiment includes: an input array for inputting an array of light beams; at least a portion of a lens; a plurality of micromirrors located at a distance away from the lens that is approximately equal to the focal length of the lens; one or more mirrors located at a distance away from the lens that is approximately equal to the focal length of the lens; and one or more delay blocks, at least a portion of which are located at a distance away from the lens that is approximately equal to the focal length of the lens. The micromirrors may include a plurality of individually controllable pixels for directing one or more light beams in the array of light beams through the lens and onto either a mirror or a delay block.
