Automated recording and testing of holographic optical element arrays

The availability of an inexpensive, self-processing, environmentally stable material with good spatial frequency response would necessarily improve th e possibility that further successful applications of holography would emer ge. One possible recording material is an acrylamide based photopolymer sys tem. To further the development of this system a bulk testing system is dev eloped. To achieve this a computer controlled automated rig for the recordi ng and testing of Holographic Optical Elements, H.O.E.s, becomes a necessit y. The control;software of the automated rig war implemented using LabView; and incorporates an inverse scatter analysis program, which can be used to extract the refractive index modulation and the thickness of the gratings.
