Abstract

Aiming at problems caused by small deformation of high linearity required long tube

a measurement system for curvatures of long tube using PSD sensor is designed and structure and operational principle of two-dimensional（2D） PSD and the computational principle of curvature are analyzed.Output signal of PSD is processed by STC89C58 MCU

and measurement result is displayed.Corresponding relation between coordinate position of light-spot and output voltage is obtained.Communication between MCU and upper PC

data analysis and processing

and system control are realized.At the same time

the effect of detecting error and circuit error on curvature measurement is analyzed.The test results indicate that the system can realize real-time measurement and remote control.It has advantages of fast response

stable operation and reliable detecting data

and so on.
