homocentric objective

The telecentric objective deoign of CCD size detection system is discussed with the measuring accuracy of ±0.

0 0 3mm的 CCD尺寸检测系统的远心物镜设计。

For laser range_finders to measure target′s distance accurately and creditably it is important that three_optic_axes are accurately adjusted to be parallel to each other with eccentric object_glass_frame and rings.

由于这种光轴校正训练难以在实物上开展,所以本文以激光测距仪瞄准物镜具有偏心物镜框、环这种常见的双偏心结构为例,研究了精确校正瞄准与激光发射两光轴平行的仿真模拟所需的理论计算公式。
