For the high power semiconductor laser the system can work in atrocious weather -such as smoking-fog. It manufactures a new 24-bit absolute angle-shaft encoder. There are more reading heads  contrastive readings  so it can eliminate the shaft error for discrepancy 90 degree square wave. It uses high precision liner array CCD  then the system may reduce error codes. The practice proves that the system can measure angle and photoelectricity collimation. The precision keeps ahead in home  so the error of one circle is minute to 1.5 in level and the precision of limit is less than 8 .
