变焦距变波长的非准确联合变换相关

Inaccurate joint transform correlation with changeable focal length and wavelength

分析了记录联合功率谱和相关点时采用不同焦距透镜和不同波长激光的非准确联合变换相关的性质,定量推导了相关点间距与透镜焦距和激光波长的关系,并由实验验证了相关点间距与透镜焦距有关。

Tbe property of inaccurate joint transform correlation is analyzed, which use changeable focal length and wavelength when the joint power spectrum and correlation spots are recorded respectively. The relation between interval of correlation spots and focal length and wavelength is deduced quantificationally and validated experimentally.
