Image plane holography.

Some of the unique reconstruction properties of image plane holography are derived from the well-known imaging equations of holography. These properties are illustrated experimentally with focused holograms using both external and locally generated reference beams. The relative advantages of lenses and hologram optical elements are presented with particular reference to local reference beam focused holography and some of the photographic film parameters which are important for optimum image reconstruction are presented. Image plane holography offers a practical technique for producing inexpensive,bright, white light displays.
