Analog optical colorimeter is used to calibrate correctingfilter so as to make it meet Luther condition. However, the calibration precision of the filter is influenced by many factors.
光学模拟测色仪采用校正滤色器使仪器满足卢瑟条件，校正滤色器的精度受多种因素的影响。

Then a linear programming method is proposed to construct the FIR filtercorrecting the amplitude and phase errors simultaneously.
