Abstract
An image sensor includes a light receiving surface on which a plurality of pixels are disposed, and detects a signal photon. A memory stores, a correspondence between a parameter indicating the position of each pixel and the wavelength of the signal photon detected by the pixel. A processor executes arithmetic processing for calculating the spectral characteristic of a sample disposed on an optical path of an idler photon. An optical system includes a moving mirror configured to apply modulation to the phase of quantum interference. The processor acquires, from a predetermined number of pixels, a variation in a detection intensity of the signal photon generated by the modulation by moving mirror, and calculates the spectral characteristic based on the visibility of the quantum interference obtained from the variation and the correspondence.
