Optical measurement device

Abstract

To provide an optical measurement device that offers an improved light utilization rate.SOLUTION: An optical measurement device for measuring measurement target light is disclosed, the optical measurement device comprising a light receiving module, a light splitting module, and a plurality of color filters. The light receiving module converts the measurement target light into first parallel light. The light splitting module splits the first parallel light into a plurality of parallel light beams to be measured. Each color filter receives at least one of the plurality of parallel light beams to be measured. The plurality of parallel light beams to be measured filtered by the plurality of color filters are used to calculate tristimulus values in the CIE color space.SELECTED DRAWING: Figure 4
