摘要： 利用光的干涉现象,通过在半平玻板上涂敷光密介质获得了有错移的明暗相间的干涉条纹,直观地展示了＂半波损失＂现象.然后推导出干涉图样分布方程,并结合实验数据计算出不同介质表面反射时产生的额外光程差,从而定量地分析了＂半波损失＂现象.同时基于导出的干涉图样分布方程对实验结果进行了计算机模拟,从另一个角度说明了＂半波损失＂现象.

Abstract: ： The ＂half-wave loss＂ phenomenon is directly ning the ＂light and dark＂ inteIfcrence fringes. Based on the shown by changing the interface medium and obtai- deduced distribution equation of interference pattern and the experimental data, we analyze quantitatively this phenomenon according to the calculation of the additional optical path difference produced by reflections on different medium surface. Moreover, the ＂half-wave loss＂ phe- nomenon is illustrated from another point of view by simulating the experimental results in the light of distribution e- quation of interference pattern.
Key words: half-wave loss, experimental research, computer simulation
