COHERENT OPTICAL HOLOGRAPHIC IMAGING

A holographic imaging system may include an optical source configured to output a source beam, a splitter configured to split the source beam into a reference beam and an object beam that is incident on a target to form a scattered object beam, and a pre-filter comprising a telecentric lens and a spatial filter. The pre-filter may be configured to receive the scattered object beam and filter diffuse light from the scattered object beam to form a filtered scattered object beam. The system may also include a combiner configured to combine the filtered scattered object beam with the reference beam to form an interference beam, and an imaging array configured to receive the interference beam and generate raw holographic data based on the interference beam.
