| 摘 要： | 为了标定试验设备空间位置,研制了一种像面位置可调的定焦距标星电视系统.星光经主镜和次镜反射后通过透镜组聚焦,成像在CCD靶面上；采用直线位移平台改变CCD靶面沿光轴方向的位置,直线位移误差不大于0.002 mm,解决了由于温度变形使星像偏离CCD靶面产生成像不清晰的问题.通过可见光探测标星试验验证,定焦距标星电视系统的...

| Abstract: | In order to determine the position of the theodolite,a star-observing TV system with adjustable image position and fixed focal length was developed.The incident ray from stars reflected by the main mirror and second mirror,was focused on the CCD target surface,after passed through the optical lens.By use of a linear displacement platform with the displacement error less than 0.002 mm to change CCD target face along optical axis,the defocus problem due to the structural deformation caused by temperature devi... |
