| Abstract: | The scanning mirror is widely used in optoelectronic system.The location of scanning mirror needes to be controlled finely.The linear CCD has the advantages of high definition and quickly response.The angle measure technique was introduced by using CPLD as processing unit and TCD1501C as sensor,including the driving sequence control design unit,differential signal output circuit unit and CCD signal detection unit.The results show that the measuring accuracy is up to 0.02 mrad. |
