METHOD FOR MEASURING BOTH POLARIZED SPECTRAL RESPONSE AND NON-POLARIZED SPECTRAL RESPONSE OF SAMPLE AND METHOD FOR DETECTING THE SAME, AND METHOD AND COLORIMETRIC DEVICE FOR MEASURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a colorimetric device capable of measuring both the non- polarized spectral response and polarized spectral response of a sample in a single indication.;SOLUTION: The calorimetric device is capable of measuring both the non- polarized spectral response and polarized spectral response of a sample in a single indication. The device includes a light source 12 of polarized light for illuminating the sample S and a detector 18 for measuring the light reflected by the sample. A rotatable filter wheel 16 is arranged between the sample S and the detector 18. A non-polarizing band-pass filter 22 and a polarizing band-pass filter 20 in a circular shape are arranged in the wheel. Therefore, as the wheel 16 is rotated by a drive mechanism for automatically and continuously matching the non-polarizing band-pass filter 22 and the polarizing band- pass filter 20 each with the detector, it, is possible to extract non-polarization data and polarization data on the single indication by the device.;COPYRIGHT: (C)2002,JPO
