Photorefractive amplification has a number of advantages as part of a vibrometric detection system. It provides significant amplification (>20 dB) in a narrow bandwidth ( 2 MHz, limited by our equipment, and calculations indicate amplification of sig

Photorefractive optical amplification, while useful, is a slow process. Under some circumstances, however, it amplifies optical signals effectively even when one is modulated at a relatively high frequency. We determine the reasons for this capabilit

Automatic target recognition (ATR) can be accomplished by many methods, including recognition of vibrometric signatures. In many cases, ATR is enhanced by photorefractive amplification, a two-wave mixing effect in which two input beams form a dynamic
