摘要
In order to reduce the error caused by the change of temperature, the relation between three-in-one composite compensator＇s phase retardation and temperature is calculated according to the characteristic of multiple-order quartz wave-plate. The results show that the influence on phase retardation increases with the increase of temperature and order of wave-plate. The phase retardation and the angle that the second wave-plate rotates are in a linear relationship in certain ranges. However, there is also some regularity in nonlinear areas which can be determined by theoretical calculation. The calculated result is well in agreement with experiments.
