SYSTEM AND A METHOD FOR MEASURING THE REFRACTIVE INDEX OF PLATE-SHAPED SAMPLE USING THE INTERFERENCE OF TRANSMITTED LIGHT AND REFLECTED LIGHT WITH IMPROVED MEASURING ACCURACY

摘要

PURPOSE: A system and a method for measuring the refractive index of a plate-shaped sample using the interference of transmitted light and reflected light are provided to cost-efficiently and accurately measure the refractive index of plate-shaped media.;CONSTITUTION: A system for measuring the refractive index of a plate-shaped sample using the interference of transmitted light and reflected light comprises a laser light source(11), a light detecting unit(14), and a calculation unit. The laser light source irradiates beams to a plate-shaped sample(13). The light detecting unit measures the intensity of transmitted light or reflected light from the laser light source. The calculation unit calculates the relative refractive index and thickness of the sample.;COPYRIGHT KIPO 2011
