摘要

提出了一种简单、精确的光强调制分光偏振计调制器组装方法。介绍了该方法的原理，并在此基础上构建了调制器。为了验证该方法的有效性，利用自制的调制器组装了强度调制分光偏振仪的实验装置。对调制器产生的载流子进行测量，并对实验装置测得的数据进行解调。实验结果表明，在525~700nm光谱范围内，钨卤灯准直器发出的光偏振度小于10%，偏振度约为100%。这些结果与理论结果吻合较好，验证了所提方法的可行性。

Simple and precise method for assembling the modulator of an intensity modulation spectropolarimeter

A simple and precise method is proposed for assembling the modulator of an intensity modulation spectropolarimeter.The principle of the method is introduced,and the modulator is built based on the method.In order to verify the effectiveness of the method presented,the experimental device of the intensity modulation spectropolarimeter is assembled using the modulator built.The carriers produced by the modulator are measured and they are used demodulating the data measured by the experiment device.Experimental results show that the polarized degree of the light from a tungsten-halogen lamp collimator is less than 10%,but it is about 100% when the light is polarized by apolarizer in the spectral range of 525~700nm.These results are coincident with the theoretical results well,which verifies the feasibility of method proposed.

期刊介绍： The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months. The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
