Based On The Fast-spectrum Analysis Test System

As the most basic testing equipment of spectroscopy and spectrum technology, spectrometer plays important roles in the fields of remote sensing and so on.This thesis demonstrates the present and the trend of skill of spectrum technology. Due to the request of high testing speed and multi-function, we developed an auto spectrum detection instrument for spectrum transmission and reflection test of plane optical devices. The whole measurement system can be used to not only test the transmission and reflection for plane optical devices, but also the light power and chromatic values for light source. The measuring period is less than 0.3 second, spectral range can be measured is between 200nm to 1100nm, measuring precision reaches 0.5%, and the sampling interval can be adjusted on line.The third and four parts introduce the hardware constitution, software realization. The measurement system which includes light source, optical system, spectrometer and computer has its own advantage compared to other similar products. Adopted modular design method, new spectrometer software which is designed in language VC++ have four modules including data collection module, data processing module, data display module and data management module. The software have friendly interface, functionally complete menu, thus can be operated very easily.The experiment results show that this measurement technology have many merits such as high-precision, quick and convenience.At the end of the thesis, a summary analysis of factors influencing precision is discussed, and what measures can be adopted to further the system precision are suggested.
