Title:
MULTIANGLE COLORIMETER
Document Type and Number:
WIPO Patent Application WO/2016/093079
Kind Code:
A1
Abstract:
Provided is a multiangle colorimeter such that the degree of freedom in the layout of optical elements inside of the device can be improved. In the multiangle colorimeter 1, based on the detection result of at least two light rays among a plurality of light rays with differing reflection angles, the detection result of a specific light ray with a reflection angle differing from the at least two light rays in reflected light is estimated. Thereby, in the multiangle colorimeter 1, since it is possible to obtain a light detection value even at angles where there are no optical elements, the degree of freedom in the layout of members disposed in the multiangle colorimeter 1 increases. Thus, the multiangle colorimeter 1 of the present embodiment can achieve a reduction in size in comparison to conventional multiangle colorimeters in which optical elements for guiding light are disposed at angular positions where light detection values are to be obtained.
