摘要：

针对传统激光干涉仪需要手动调节光学部件问题,设计并开发了一种激光干涉仪无线测控系统,该系统可以无线调节激光干涉仪光学部件的位置。系统采用nRF2401无线射频技术,与传统的nRF2401运用相比,该系统采用奇偶校验和CRC校验的双重校验,提高无线射频传输数据的正确率。同时系统采用闭环控制,提高了激光干涉仪的精确度和稳定性,避免了光学部件的过量调节对激光干涉仪的损伤。

Abstract:

A wireless automatic control system designed and implemented according to save the need to manually adjust the optical components in traditional laser interferometers.The system can regulate the location of the laser interferometer optical components by wireless technology.The nRF2401 wireless radio frequency technology is used and the transmitted information is coded with oddeven check and CRC check,thus an obvious decreased error rate compared with that by the traditional nRF2401.Because of the use of the closed loop,the laser interferometer has an enormous improvement in precision and stability,avoiding the optical components of excessive regulation of laser interferometer.

Key words: laser interferometer;phase shifting interferometry;wireless control
