Abstract

A measurement and control system of three-dimensional（ 3D） position information of electrostatic levitation based on position sensitive detector（ PSD） is setup and structure of PSD and position measurement and control principle of electrostatic levitation are analyzed. Output signal of PSD is processed by STC12C5A60S2 MCU

corresponding relationship between suspension sample position information and output voltage of PSD is obtained

and communication between MCU and upper PC

data analysis and processing

and position control on levitation sample are realized. Use zirconium materials to carry out suspension experiment and test results indicate that the system can realize non-contact measurement of sample position information and stable suspension of sample

and it has advantages of stable operation and reliable detecting data

and so on

and this measurement system laid foundation for material suspended heating and undercooling research.
