Early holograms were recorded on photographic plates, and today such plates are still the most common holographic recording medium. However, the nature of the holographic process, plus the development of high-power coherent light sources, invited the use of materials other than photographic emulsions. As a result, holograms have been recorded in dichromatic sensitized gelatin, photoresist, electro-optical crystals, photochromic films and glasses, thermoplastics, photopolymers, amorphous semiconductors, and dye, MnBi, vesicular, and diazo films, as well as the more standard silver halide emulsions. In this review, the holographic recording ma-terials currently available are examined along with a few of their applications. Some experimental media are also studied. No effort to rank the materials is made, as the purpose of this review is simply to familiarize the reader with the various options he has in selecting a holographic recording material for his particular application. This approach is felt to be appropriate since most media currently available will form excellent holograms.
