| 摘 要： | 基于应力光学定律和弹性热应力理论，导出双折射的光程差与主应力差之间的关系。利用光学弹性仪进行了实验测试，研究了温度变化下应力对树脂光学镜头成像质量的影响。从28℃～68℃的温度范围内，实验获得了树脂镜头的热应力等色线和不同温度、静置情况下的树脂镜头的热应力等色线干涉条纹的图像。得出结论：温度变化在树脂镜头中产生热应力，但不会产生应力集中，在温度恢复时没有残余应力，在40℃的温度变化内不会影响光学树脂镜头的成像质量。 |
| 关 键 词： | 弹光效应 温度效应 双折射 热应力 光学树脂镜头 |

| Abstract: | Based on the stress optics law and the theory of elasticity thermal stress, the relation between optic path difference of double refraction and main stress difference is derived. The effect of the stress on the imaging quality of optic colophony lens was examined in changing temperature environment with a photoelasticimeter. At 28℃～68℃, the isochromatic line of optic colophony lens of thermal stress was determined, and the interference fringe patterns were obtained at different temperatures and main stress differences. It is concluded that the thermal stress produced by temperature change does not converge, and no residual stress exists when temperature recovers. The image quality of the optic lens is not affected in 40℃ temperature variation range. |
| Keywords: | elasto-optical effect temperature effect double refraction thermal stress optic colophony lens |
