Evaluation of Amplified Image Characteristics of a BSO Crystal

Abstract

Image amplification by two-wave missing in a BSO crystal is investigated. Amplified images are observed to have higher gray levels, with an average relative gain of 5.9. Contrast range is enhanced from 0-to-58 to 0-t0-98 and the overall brightness is increased by a factor of 2.7. The response function of the image amplification system shows sensitivity at higher spatial frequencies and is similar for two different images.
