| 摘 要： | 介绍一种用于光学测量投影仪的角位移测量仪。它通过硬件电路对一个旋转编码器输出的角位移信号进行辨向和计数,再使用一个微处理器对辨向信号和计数信号进行处理,得到被测工件在Z旋转方向的位移值,最后对位移测量值进行误差修正,得到该仪器的测量分辨率为1’且测量精度为±3．9’。实验表明：所研制的角位移测量仪具有准确、可靠的特点。

| Abstract: | An angular displacement measurement instrument used for optical measuring projector is introduced. The signals from the rotary encoder that indicate the value of the angular displacement are identified and counted by a circuit. The identified and counted signals are processed by a microprocessor to obtain the displacement value of the Z rotary direction. An error correction algorithm is implemented to compensate the measuring values. The resolution of 1′ and the measuring precision of ±3. 9′of the instrument are obtained. The experiment results show that the characteristics of the instrument are precise and reliable. |
