The measurement of moving object with high speed based on liner TDI-CCD

The working principle of TDI CCD Image sensor was introduced,the synchronism controlling problem of image sensors line scanning rate and objects moving speed in intersection testing system based on TDI CCD were analyzed the dynamical alteration of counters initial values were brought forward while making region real time speed testing as the benchmark to realize the real time synchronism of line scanning rate and objects moving speed. The testing data of ball cartridges testified the feasibility of TDI CCD in outfield testing.
