分析了温度对三线阵测绘相机传递函数和交会角的影响
通过热光学计算确定了测绘相机的热控指标。首先
在设定测绘相机热载荷状态的基础上
用有限元方法分析了温度场及热弹性变形;利用Zernike多项式进行波面拟合
代入光学软件考察温度对光学系统传递函数的影响
得到测绘相机光学传递函数在假定温度场作用下的下降系数。然后
进行了测绘基座的热尺寸稳定性分析
并在此基础上考察了温度对测绘相机交会角的影响。实验显示
上述分析避免了热控设计的过设计或设计不足
为制定合理的热控设计指标提供了数据依据。
The effect of temperature on the transfer function and space intersection angles of a three-line mapping camera was analyzed and the thermal control index of the three-line mapping camera was calculated by a thermal-optical method. First
the temperature field and thermal elastic deformation were analyzed with Finite Element Method(FEM) on the basis of hypothetic thermal loads and the wave surface fitted with a Zernike polynomial was put into an optical software to explore the effect of temperature on the optical transfer function. Then
the temperature regressive data of transfer function for the mapping camera were obtained in an assumed temperature field. Furthermore
the thermal size stability of a mapping base was analyzed and the effect of temperature on the intersection angles of the three-line mapping camera was gotten. Experiments show that the over or short thermal control designs can be avoided with the proposed method and it can provide reasonable data for thermal control indexes.
