Abstract
A measurement apparatus (10) includes a spectroscope (11) configured to extract a specific wavelength component from incident light, a photodetector (13) configured to output a signal according to an intensity of the extracted wavelength component, and a processor (16). The processor (16) is configured to acquire, for each wavelength interval in a plurality of wavelength intervals into which a wavelength range to be measured is divided, a first signal outputted from the photodetector in a state in which light is blocked and a second signal outputted from the photodetector according to the intensity of the incident light in a state in which light is not blocked, and output a difference between the second signal and the first signal as an optical spectrum of the wavelength interval.
