改善数字全息再现像质量的背景强度补偿法
Background intensity compensation method for improving the reconstructed image quality of digital hologram
摘要
Abstract
Aiming at completely eliminating the influence of CCD' s noise and scattered background light on the reconstructed image of digital hologram, based on the hologram subtracting reference light intensity and object light intensity ( HRO) subtraction method and hologram subtracting reference light intensity, object light intensity and CCD' s noise( HRON) subtraction method, the background intensity compensation method ( BICM) was proposed. The quality of the experimentally reconstructed images of the original hologram and holograms processed by BICM was compared. Results show that BICM could effectively improve the quality of reconstructed image and relax the requirement on digital hologram recording environment.关键词
