Abstract
An imaging device includes a light source which irradiates an infrared light including one or more wavelength to a subject; a lens which forms an image of the infrared light transmitting the subject or being reflected from the subject; an infrared detection device including a plurality of pixels which are sensitive to the wavelength; and a filter array which is provided in proximity to the infrared detection device between the lens and the infrared detection device and including a plurality of wavelength filters having different transmission wavelengths.

An imaging device comprising:
- a light source which irradiates an infrared light including one or more wavelengths to a subject;
- a lens which forms an image of the infrared light transmitting the subject or being reflected from the subject;
- an infrared detection device including a plurality of pixels which are sensitive to the wavelength;
- and
- a filter array which is provided in proximity to the infrared detection device between the lens and the infrared detection device and including a plurality of wavelength filters having different transmission wavelengths,
- wherein the filter array of the plurality of wavelength filters has transmission wavelengths that change continuously in one direction on a plane and that are the same as each other in a different direction which is orthogonal to the one direction.
An imaging device comprising:
- a light source which irradiates an infrared light including one or more wavelengths to a subject;
- a lens which forms an image of the infrared light transmitting the subject or being reflected from the subject;
- an infrared detection device including a plurality of pixels which are sensitive to the wavelength;
- and
- a filter array which is provided in proximity to the infrared detection device between the lens and the infrared detection device and including a plurality of wavelength filters having different transmission wavelengths,
- wherein the filter array has a structure in which a resonance layer and an interference layer are laminated;
- and
- wherein the resonance layer and the interference layer are arranged such that the resonance layer is located on the image-forming optical member side and the interference layer is located on the infrared detection device side.
