光电跟踪传感器的非线性校正

The Nonlinear Correcting on the Photoelectric Sensor for Seam Tracking

利用二极管及结型场效应管的非线性特性，对光电传感器输出信号进行了非线性处理，有效地消除了由于传感器中光电三极管的非线性而引起的附加干扰，提高了传感器的抗干扰能力，增强了实际应用的适应性．

The signal from a photoelectric sensor for seam tracking was processed nonlinearly with a nonlinear circuit. Because of the nonlinearity of the diode and JFET in the circuit, the disturbance caused by the nonlinearity of the pho- totransistor in the sensor was reduced effectively. The ability in anti-interference of the sensor was improved.
