自动变扫描控制技术

The Controlling Technology of Automatic and Changing Scan

线阵 CCD 光电传感器在激光自准直经纬仪中的应用,为经纬仪实现高精度、高灵敏度、重量轻、体积小等特点带来了很多的优越性。但是在实现 CCD 驱动电路设计时,我们经常遇到一些问题。为了解决上述问题文中提出一种新的线阵 CCD 驱动电路中的自动变扫描控制的设计方法,根据光源的强度自动有效地控制曝光时间,提高测量精度。

The aplication of linear CCD in the system of laser auto collimation theodolite brings a lot of advantage,such as high precision,high delicacy,light weight,etc.But we also meet the problems for designing the CCD driving circuits To solve the problems,In the paper a new designing method of automatic and changing scan control is provided.It automatically and effectively control the time of exposure according with the light intension and improve the measuring precision.
