SPECTROSCOPIC IMAGING APPARATUS AND SPECTROSCOPIC IMAGING METHOD

摘要

A spectroscopic camera is provided with a pair of reflecting films, and a wavelength variable interference filter including an electrostatic actuator which can change a size of the gap between the pair of reflecting films, an imaging unit which includes a plurality of pixels which is disposed in a two-dimensional array structure, and receives the light transmitted to the wavelength variable interference filter, and a received-light wavelength acquiring unit which acquires a central wavelength of the light which is incident on the pixel with respect to each of the pixels in the imaging unit, in which the received-light wavelength acquiring unit acquires the central wavelength based on an incidence angle in a position where the light which is received in each of the pixels is incident to the pair of reflecting films.

1. A spectroscopic imaging apparatus comprising:
an imaging unit that includes a plurality of pixels, and receives light guided by a light condensing unit; a wavelength variable interference filter that includes a pair of reflecting films and a gap changing unit which is able to change a size of the gap between the pair of reflecting films, and is disposed on an optical path of the light incident on the imaging unit; and a received-light wavelength acquiring unit that acquires a central wavelength of the light which is incident on each of the plurality of pixels, wherein the received-light wavelength acquiring unit acquires the central wavelength based on an incidence angle in a position where the light which is received in each of the plurality of pixels is incident to one among the pair of reflecting films.
