SPECTROMETER

摘要

A spectrometer includes: a wavelength-variable interference filter that can change a wavelength of selected light and disperses light from a measurement target; an imaging unit that receives light components with a plurality of wavelengths which are dispersed by the wavelength-variable interference filter and acquires a plurality of spectral images; a positional deviation amount detection unit that selects a standard image from the plurality of spectral images acquired by the imaging unit and detects a positional deviation amount of a pixel position which receives light from a predetermined position of the measurement target between the standard image and at least one of the spectral images other than the standard image; and a position correction unit that positions the spectral images other than the standard image on the basis of the detected positional deviation amount.
