Abstract
High precision micro displacement measurement framework is fundamental for drilling strain gauges. We try to combine the linear least square (LLS) method of Duffing chaotic detection (DCD) to replace the traditional lock-in amplifier method in drilling strain gauges. Simulation results showed that the method of "LLS+DCD" is better than lock-in amplifier method in the detection accuracy. Even more, the design and realization of "LLS + DCD" method is easier than lock-in amplifier method.
