Abstract
A method is shown of recording a hologram without spatially offsetting the reference beam. The temporal frequency of the reference beam is offset and the the resultant intensity pattern is scanned using a television camera. The desired conjugate image signals are separated from the undesired terms using a bandpass filter on the electrical signal. This method significantly reduces the resolution requirements of the hologram recorder.Keywords
