透射光谱法测量滤光片参数的实验研究

Experimental Study of Filters Based on Spectral Transmission Measurement

利用海洋光纤光谱仪将光信号经分光系统和CCD阵列转换为各个波长范围的电信号,用Spectra Suite软件进行分析处理,获得相应的光谱信号曲线。实验结果表明,不同滤光片的透过率曲线不同,分析了滤光片透过的波长范围及其各自的透过率,通过各个滤光片的测试结果,了解各滤光片的应用领域。

Using the ocean fiber optic spectrometer,optical signal passes through the spectral system and CCD array to be converted into electrical signals of different wavelength range,then Spectra Suite software is used to analyze and process to get the corresponding spectral signal curve. The results show that various filters have dif-ferent transmittance curve. The range of wavelength and their respective transmittance are analyzed for these fi-bers. Through each filter test results,the field of each filter application is understood.
