Title:
OPTICAL DEVICE, OPTICAL DEVICE OPERATION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2022/181094
Kind Code:
A1
Abstract:
This optical device comprises a first optical element, a second optical element, and a sensor. The first optical element selectively transmits, from among the light incident on the first optical element, first light having a first wavelength band and second light having a second wavelength band. The second optical element corrects the radiance ratio between the first light and second light by at least reducing the amount of the second light from among the first light and second light. The sensor receives the first light and second light that have had the radiance ratio thereof corrected by the second optical element and outputs a first signal corresponding to the irradiance of the first light and a second signal corresponding to the irradiance of the second light.
