This paper presents several frequently used methods of angle measurement that utilize laser  including:autocollimation angle measurement  angle measurement based on internal-reflection effect  laser interference angle measurement  angle measurement with ring laser and angle measurement with CCD. The principle  actualities  application situation  superiority and defects of each method are discussed.

The experimental results show that after noise processing  the imaging quality is reduced  etc. According to the features of noise  the output S/N has been raised to about 50 dB. 2010 IEEE.  so that it is necessary to study the noise characteristics of TDI-CCD. There are two categories of noise  this paper has studied the corresponding noise-processing technology. For dark current noise  one is the inherent noise  refrigeration is taken  including shot noise  dark current noise  fixed pattern noise and transfer noise etc.
