CURED STATE OF RESIN MONITORING DEVICE AND CURED STATE OF RESIN MONITORING METHOD

摘要

PROBLEM TO BE SOLVED: To reduce the cost of acquiring a fluorescent image for each wavelength at the same time, as one aspect of the invention.SOLUTION: A camera 26 has a plurality of pixels 50A, 50B. A pair of filters 44A, 44B are disposed on an optical path between a resin 36 and a pair of first polarizers 46A, 46B, each transmitting light of mutually different wavelengths. The pair of first polarizers 46A, 46B is disposed on an optical path between the pair of filters 44A, 44B and a plurality of second polarizers 52A, 52B, converting incident light into two polarized beams 48A, 48B differing in the direction of polarization from each other. The plurality of second polarizers 52A, 52B is provided facing each of the plurality of pixels 50A, 50B, each transmitting each of the two polarized beams 48A, 48B.
