  • Based on linear frequency modulation continuous wave (FMCW) technique,we have developed a distance measurement method for non-contact and non-integrating error measurement.A tunable GaAlAs diode laser is used as a chirp signal source,the distance is detected by calculating the beat frequency.The dynamic range of the system is about 1m,and the measurement accuracy of 10-3 is obtained.

Abstract: Based on linear frequency modulation continuous wave (FMCW) technique,we have developed a distance measurement method for non-contact and non-integrating error measurement.A tunable GaAlAs diode laser is used as a chirp signal source,the distance is detected by calculating the beat frequency.The dynamic range of the system is about 1m,and the measurement accuracy of 10-3 is obtained.
