| Abstract: | The design of the medical treatment of ophthalmic laser instrument controller is described in this paper.It uses the semiconductor pumped Nd: YAG laser which has two working modes: pulse mode and continuous mode.Working in pulse mode,the microcontroller’s timer controls the laser pulse frequency.The controller uses the DAC(Digital-to-Analog Converter) to produce a voltage signal to drive the power control module to control the laser energy.The color LCD(Liquid Crystal Display) with touch-screen module is used to design the interface.Through the touch screen,the working mode and operating parameters are set.The circuit of system is introduced,and the program flow chart is given in the last. |
