Abstract: An optical property measurement apparatus includes a pulse formation unit, a waveform measurement unit, and an optical system. The pulse formation unit is capable of changing a temporal waveform of pulsed light in accordance with a type of optical property to be measured. The waveform measurement unit measures a temporal waveform of the pulsed light output from a measurement object after being incident on the measurement object. The optical system has an attenuation unit with an attenuation rate with respect to one wavelength component constituting the pulsed light larger than an attenuation rate with respect to another wavelength component constituting the pulsed light. The optical system is capable of switching between a first state in which the attenuation unit is arranged on an optical path of the pulsed light output from the measurement object and a second state in which the attenuation unit is not arranged on the optical path.

Abstract: An iterative Fourier transform unit of 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. The coefficient has a value with which a difference between the function after the multiplication of the coefficient and the temporal intensity waveform function after the Fourier transform is smaller than a difference before the multiplication, and a ratio of the difference is smaller when an intensity is higher at each time of the function before the multiplication.
