摘要

High precision micro displacement measurement framework is fundamental for drilling strain gauges. We replaced the traditional lock-in amplifier method by the linear least square (LLS) based on Duffing chaotic detection (DCD) in drilling strain gauges. Simulation results showed that LLS based on DCD has a relative error 7.7% when SNR= -20.79 dB. It is 410.1% lower than lock-in amplifier method in the detection. Even more, the design and realization of LLS based on DCD is easier than lock-in amplifier method.
