摘要
在对数字全息技术进行严格理论分析的基础上 ,指出随单个 CCD像元尺寸的减小可能被记录物体的横向尺寸将变大 ,所允许的纵向尺寸却变小 ;另一方面其系统误差和被测量值本身的大小成正比 ,和横向分辨率成反比。
Basic characters of digital holographic profiling including its system error, resolution, imaging depth, and the size limit of the recorded object are theoretically discussed in this paper. It is pointed out that the system error of digital holographic profiling is in proportion to the squared size of the CCD chip and in inverse proportion to the recording distance. This paper also pointed out that the resolution of digital holographic profiling and the maximum size of the recorded object are all proportional to the size of CCD chip and in iverse proportion to the recording distance, while its imaging depth increases with the recording distance.
