摘    要:三线阵立体相机的光学系统决定了相机的外形尺寸和布局,保证相机的小型化、轻量化及稳定性是十分必要的,针对光学系统设计的指标要求,分析、比较了各种光学系统结构型式,设计了满足测绘要求的像方远心光学系统。设计的光学系统成像质量好,在Nyquist频率77lp/mm时,正视相机全视场的平均传递函数为0.613;前、后视相机全视场的平均传递函数为0.578。装调完成后对光学系统成像质量进行了检测,各相机光学系统传递函数的测试值均在0.451以上,满足对测绘质量的要求。

关 键 词:三线阵CCD相机  光学设计  光学传递函数

Abstract:The size and structure of three line array stereoscopic mapping camera is mainly determined by the optical system. It is necessary for certain the miniaturization, lightening and high reliability of the camera. Kinds of optical system configurations are analyzed and compared by the requirements of the optical system. Telecentric system is adopted to meet the requirement of stereoscopic mapping. The MTF value of each lens is close to the diffraction limit at Nyquist frequency of 77 lp/mm. The tested result shows the MTF of each optical system can reach to 0.43 at Nyquist frequency of 77 lp/mm, which can meet the requirements of precision for the mapping camera.
Keywords:mapping camera  optical design  MTF
