石英晶体有着较大的温度膨胀系数, 因而温度变化会引起石英晶体制作器件的使用误差。为了减小这种误差, 研究了二元复合式补偿器相位延迟随温度的变化情况。结果表明, 温度变化越大, 波片级数越大, 补偿相位受到的影响也越大; 理论计算表明, 补偿相位在一定的温度范围内与起偏镜转动的角度成线性关系。实验结果与理论结果相一致。该研究结果对于复合补偿器在不同环境下的正确使用有一定的参考价值。

Quartz crystal has a biggish temperature expansion coefficient, therefore temperature variation will cause use errors for quartz crystal devices. In order to reduce this error, we study the relation between composite compensator’s phase retardation and temperature variation. The results show that the bigger the temperature change is and the order of wave plate, the bigger the influence on the phase retardation is. The phase retardation and the rotation angle of the polarizer exhibit a linear relation in definite temperature range. The calculated result is well in agreement with experiments. Our results provide a useful referrece for the proper employment of composite compensator under different situations.
