LINEAR CCD SUB-PIXEL IMAGE CELL MEASUREMENT SYSTEM BASED ON DRIVING PULSE DELAY
基于驱动脉冲延迟的线阵CCD亚像素测量系统

Distance between the image cell and its light-sensing area of linear CCD cannot be much small,so it has restricted application in high precision measurement system.As the spatial information is able to be converted to the time information changing in one pulse unit by the design of interval precise delay driving pulse.It is proved that the limitation on accuracy of linear CCD image cell can be breakthrough effectively,and so the sub-pixel measuring can be achieved and detected by the displacement platform o...
