Document Type and Number:
WIPO Patent Application WO/2019/082251
Kind Code:
A1
Abstract:
In order to detect, with high accuracy, optical characteristics in an infrared region of a sheet of paper, this optical sensor used for detecting the optical characteristics comprises: a light-emitting unit having a light-emitting element corresponding to at least three infrared bands included in an infrared region with a wavelength of 1,100 nm or less; and a light-receiving unit having a light-receiving element that is sensitive to the at least three infrared bands. The light-receiving unit is configured so as to detect, using the light-receiving element, the intensity of light in each of the at least three infrared bands.
