| Abstract: | Based on introduction on the fundamental principles of PSD(position sensitive detector),the design method of infrared position sensor is presented,which is mainly composed of PSD and applied to rectify a deviation system.The principle and structure of the sensor are described.The related design for hardware and software is given.And not only the factors affecting localization accuracy of the sensor are analyzed,but also the improvement method is proposed.The maximum detection distance of the sensor is ±18.5mm and the sampling frequency is 1.5kHz .The experiments show that the accuracy of the sensor can reach 0.1mm. |
