Abstract:
The paper considers an algorithm for partial encoding of the amplitude by a binary phase with a linear dependence of the phase step width in the coding cell on the amplitude. The parameter of the degree of encoding is the threshold amplitude level, below which the amplitude is encoded in a phase, and above which it is replaced by a constant value. The method is applied to the calculation of phase spatial Fourier filters consistent with the two-dimensional images.
