Title:
SIMULATION METHOD AND IMAGE PROCESSING APPARATUS
Document Type and Number:
Japanese Patent JP2022026450
Kind Code:
A
Abstract:
To provide a simulation method that can prevent a deterioration in the accuracy of data obtained by sampling a frequency space at an unequal interval.SOLUTION: A simulation method has a step of acquiring the power spectrum of the phase fluctuation of a light wave and a random number, and a step of performing unequal interval fast Fourier transform by using the power spectrum and random number. In the step of performing the unequal interval fast Fourier transform, convolution is performed in order from a frequency having a smaller value of a discretized power spectrum.SELECTED DRAWING: Figure 1
