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
