Abstract:

The significance of this research is the evaluation and characterization of possible recording materials for holographic optical elements. Seven recording materials were evaluated for use as holographic optical elements through measurement of holographic sensitometric and readout parameters and investigation of their environmental stability. The seven materials included four volume phase materials, bleached photographic emulsions, dichromated gelatin, photopolymer, and thick thermoplastics and three thin phase materials, photoresist, iron oxide, and photoplastics. The holographic response of each material was characterized through measurements of exposure sensitivity, diffraction efficiency, signal-to-noise ratio, frequency response, and spectral variation of readout efficiency. Environmental stability was determined by monitoring the holographic parameters over a wide temperature and humidity range, under prolonged UV exposure, and by measuring the nondestructive readout intensity range.
