计算全息术制备特种空间滤波器
Spatial Filters Using Computer generated Hologram (CGH)
摘要
研究了用计算全息制作二进制振幅调制纯位相空间滤波器的方法,以及它与其它几种滤波器性能的比较。实验结果表明,计算全息制的振幅调制纯位相空间滤波器在相关峰的锐度、Horner效率和抗噪能力上俱佳。
Abstract
The binary amplitude modulated phase only spatial filter (BAMPOF) is studied and different filters are compared to access the BAMPOF′s performance. The study shows that the BAMPOF has good features regarding the sharpness of the correlation peak, Horner efficiency and noise tolerance. So, the applications of it in the optical pattern recognition is promising.
