摘要
An iterative Fourier transform unit in a modulation pattern calculation apparatus performs a Fourier transform on a waveform function including an intensity spectrum function and a phase spectrum function, performs a replacement of a temporal intensity waveform function based on a desired waveform after the Fourier transform, and then performs an inverse Fourier transform. The iterative Fourier transform unit performs the replacement using a result of multiplying a function representing the desired waveform by a coefficient, and the coefficient has a value in which a difference between the function after the multiplication and the temporal intensity waveform function after the Fourier transform is smaller than a difference before the multiplication of the coefficient.
