LIGHT DETECTOR, PRINTER, AND IMAGE DISPLAY UNIT

摘要

PROBLEM TO BE SOLVED: To simultaneously detect light with different wavelengths with high accuracy.SOLUTION: A light detector divides a beam of light which has passed through a spectroscope for selectively allowing light with a desired wavelength through into a plurality of beams of light on the basis of the wavelength, and guides the divided plurality of beams of light to different light paths. The plurality of beams of light guided to the different light paths are respectively made incident to a plurality of light reception parts.
