METHOD AND APPARATUS FOR INTERFERENCE PATTERN RECORDING |
摘要 |
Interference pattern recording is accomplished by simultaneous holographic and Lippmann holographic methods by directing the otherwise wasted radiation of the noninformation modulated beam back into the storage medium. Interference again takes place with the information-bearing beam to form another image in the medium. After processing the medium, reconstruction of the stored information is performed and a substantially stronger output image is generated.
