Optical fiber head optimized for colorimetry applications

摘要

One of the main problem of colorimetry is sensitivity of the optical fiber sensor for displacement of examined object. It means that the sensor also works as proximity or distance measurement sensor. In order to omit a problem of cross-sensitivity of the sensor we have analyzed several configurations of optical fibers inside sensor head. Results of the tests of several types of sensor head are presented. The best solution of fiber-optic head for colorimetric application is discussed as well. In conclusions some other applications of the optimized optical fiber sensor head are shown.
