Document Type and Number:
WIPO Patent Application WO/2022/024917
Kind Code:
A1
Abstract:
An embodiment of the present invention provides an imaging device, an adjustment method, and an adjustment program capable of acquiring a multispectral image having good image quality. In one aspect of the present invention, this imaging device, which is located on an image side of another optical system, comprises: a multispectral camera that captures images for a plurality of wavelength bands; a field lens that relays between another optical system and the multispectral camera; and an adjustment mechanism that adjusts a conjugate relationship between an exit pupil location of another optical system and an entrance pupil location of the multispectral camera. The multispectral camera includes: an optical member disposed at or near a pupil location and having a plurality of opening regions having different centers of gravity; a wavelength polarizing filter unit that has a plurality of optical filters disposed in the plurality of opening regions and polarizing filters disposed in the plurality of opening regions; an imaging element; and a processor.
