OPTICAL APPARATUS AND METHOD FOR DETECTING PHOTOLUMINESCENCE AND CURVATURE USING THE SAME

摘要

PURPOSE: An optical device and an illuminance and curvature measurement method using the same are provided to effectively measure the illuminance and curvature of a material at the same time. CONSTITUTION: An optical device(100) comprises an irradiator(130), a first detector(142), and a second detector(144). The irradiator projects two or more light beams to a sample. The first detector analyzes illuminance of the sample by one of the light beams and measures the energy band size of the illumination. The second detector analyzes the light reflected off the sample and detects the curvature of the sample.
