Holographic image formation using phase plates with incoherent imaging property.
An incoherent image synthesis method using a recently developed grating modulated phase plate has been presented in order to reduce unwanted noise components in the reconstructed images. A study in connection with this method leads us to the analytical derivation of a desirable phase plate with a specified phase sequence. The analytical description presented here, with particular emphasis on obtaining the imaging property in coherent holographic imagery identical to that in incoherent imagery, shows that the derived phase plate enables us to get the reconstructions with far less undesirable irregular intensity fluctuations or noiselike pattern. Some experimental confirmations are given to make sure of the analysis.
