| Abstract: | A reflective photoelectric displacement sensor with columnar light-beam for the measurement of strip edge position is described. The sensor consists of a light source, an optical system, a triple reflector, the silicon cell and some other electronic devices. Luminous flux variation reflected from the triple reflector due to the displacement of strip edge is detected by the sensor. The nonlinear input-output characteristic of the sensor is discussed on the basis of photoelectricity theory. Both the optimum first-order polynomial and third-order polynomial are proposed for fitting the output curve of the sensor. Error experiment and analysis have been made. The measuring range of the sensor is from -24 mm to 24 mm. The actual error is from -1.253 mm to 1.213 mm by first-order polynomial and -0.185 mm to 0.172mm by third-order polynomial. |
