Abstract
An imaging device for reducing a processing load of signal processing using two images of different wavelengths, and a method of operating the imaging device. The phases of two incident light beams having different wavelengths are matched, the two incident light beams are polarized into the same polarization direction, a wavelength of one incident light beam of the two types of polarized incident light beams is matched with a wavelength of the other incident light beam, a phase difference is adjusted such that the phase difference between the one incident light beam and the other incident light beam is π, the two types of incident light beams being matched with the wavelength of the one incident light beam, and an imaging element simultaneously receives the two types of incident light beams adjusted such that the phase difference is π, thereby, optically acquiring the subtraction results of two types of power.
