Recording of High Spatial Frequency Using two Confocal Lenses in Digital Holography
The angle of an incoming laser light ray is reduced by an amount equal to the ratio of focal lengths of two confocal lenses. This lowers the spatial frequency of the interference pattern. By using an optical setup of confocal lenses, the area of the zero-order diffraction is reduced by the square of the ratio of the two focal lengths during numerical reconstruction.
