摘要：

In　this　paper,　TDI-CCD　was　applied　to　dental　X-ray　panoramic　radiography,　in　order　to　improve　the　image　resolution　and　realize　the　direct　digital　radiography.　The　drive　pulses　of　TDI-CCD　are　generated　by　CPLD,　causing　storage　and　shift　of　photoinduced　charge.　TDI-CCD　can　operate　normally　under　the　action　of　drive　pulses.　Aiming　at　reducing　the　noise　of　the　CCD　output　signal,　signal　processing　circuit　was　designed.　And　the　noise　can　be　greatly　restrained　through　capacitance　coupling,　filtering,　clamping,　sampling　and　holding　circuits.　The　processed　CCD　signal　is　convenient　for　A/D　conversion.　©　2012　IEEE.
