The amplitude transmittance of one of them is assumod to be the same function as the coherent impulse response of the system, and that of the other being complex conjugate of the former.
它包括使用两个复数透光片，其中一个振幅透射率等于该系统的相干脉冲响应函数，另一则为其共轭复数。

The series density formulae of the binary phase grating are obtained from the general complex amplitude transmittance formulae through Fourier integral.
