Patent abstract
A ladar device that has a linear frequency-modulated laser source that produces a primary beam. An optical shear generator spectrally shears the primary beam into no less than three sensing beams. An optical output delivers at least one of the sensing beams toward a target. The sensing beams reflect from the target to produce reflected beams. An optical receiver receives the reflected beams and produces reflected beam signals corresponding to characteristics of the reflected beams. A processor receives the reflected beam signals and produces a deviation matrix, without the use of a local oscillator. The deviation matrix is used to produce a reconstruction of the target, which is output on an electrical signal output.
