摘要

An iterative Fourier transform unit 22a in a modulation pattern calculation apparatus 20 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 22a 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. As a result, a modulation pattern calculation apparatus, a light control apparatus, a modulation pattern calculation method, and a modulation pattern calculation program capable of preventing a solution from being led to a local solution during an iterative Fourier operation and accurately calculating an intensity spectrum or a phase spectrum to bring a temporal waveform of light close to a desired waveform are realized.
