Abstract: Aiming at spatial coordinates measurement,a new PSD laser tracking measurement system based on triangulation was designed,and operational principle was introduced,then designed the the control system applied to the present measurement system. PC control system consist of IPC and motion control card PCI8134, Gyroscope MPU6050 collecting angle information, PSD processor amplifying the data, AD7606 converting analog signals to digital signals, NRF24L01 module handling data transportation, embedded microcontroller STM32 processing data. The results indicate that the measurement system is stable and reliable,and applied to the laser tracking control system successfully.
Key words: trigonometry; laser tracking; control systems; position sensitive device(PSD)
