NG-TTL Python scripts and data

NG_TTL.xlsx records the LPS values detected by the detector when an aberrated measurement beam interferes with a local Gaussian beam under different incident fields of view for an off-axis four-element telescope.These two Python scripts use the LPF method to calculate the LPS values in an XLSX file.

NG_TTL.xlsx 记录了离轴四元望远镜（off-axis four-element telescope）在不同入射视场下，存在像差的测量光束与本地高斯光束发生干涉时，探测器所测得的LPS值。两段Python脚本可采用LPF方法计算XLSX格式文件中的LPS值。
