目前振幅和时间脉冲式光电传感器使角度和长度的测量值达到了极高的精度。虽然传感器本身的误差可以分别减少到10~(-2)微米和10~(-2)角秒,但是这个结果是在实验室得到的,因为传感器的测量精度在很大程度上取决于信号源参数的稳定性和信息传输通
Current amplitude and time pulsed photoelectric sensors achieve extremely high levels of angle and length measurements. Although the error of the sensor itself can be reduced to 10 -2 micrometers and 10 -2 angular seconds, respectively, this result is obtained in the laboratory because the accuracy of the sensor measurement depends largely on the signal source Parameter stability and information transmission links
