Optical Fiber Sensing Measurment Theory And Apply Research

With the development of industries in color, the color quality control and formulation of the forecast demand for more and more, in the conventional system of the problems encountered in the use of more and more, therefore all the more precise and complex optical model, the algorithm Technology and corresponding color measurement systems continue to be made, research and development to meet the different levels and application of conventional and special requirements.This article introduced one kind of fiber sensing computer color measurement system which based on the PC2000 miniature optical fiber spectroscope. The system mainly by the fibre-optics probe, the miniature spectroscope, the CCD detector and the computer analysis software is composed. The sample spectrum signal conducts from the self-made fibre-optics probe to the spectroscope, undergoes the preliminary analysis to be possible to obtain in the visible light scope the spectrum data. The self-made fibre-optics probe may realize the non-contact survey, and can eliminate the stray light to the survey the influence. The fibre-optics probe volume is small, may realize to is measured the object the micro area survey; Fibre-optics probe's spotlight ability is strong, is advantageous to the weak spectrum survey. Analyzes the software take the colorimetry and the color measurment theory as the foundation, may carry on the detailed analysis to the sample spectrum data, including the spectrum curve, the colorimetric parameter, three stimulation value curve, the index of reflection curve, the color chromatic aberration as well as the color reappearance and so on, the good user interface, causes to measure that the color system tends the intellectualization. The color reappearance was first through had nothing to do with the equipment has carried on the characteristic analysis to the computer coloration RGB space and the CIEXYZ space which, then established both's corresponding relationships to realize. In addition this system also to clinical roasted the porcelain tooth's color measurment to conduct the research, and used in this system the oral cavity living specimen tooth's survey, the test result analyzes this software to be able quite convenient and accurate realizes roasts the porcelain tooth color the match, this has provided the new method for the new oral cavity material's examination, was the system practical application, the production has laid the foundation.
