基于MSP430的红外光源控制系统及其硬件设计

北京理工大学珠海学院2020届本科生毕业设计MSP430-based infrared light source control system and its hardwaredesignAbstractWith the rapid development of integrated circuit technology,microcontroller technology,and spectroscopy technology,applications based on the spectral characteristics of infraredlight are becoming more and more extensive.Infrared light sources are widely used in gasanalysis,laser ranging,robot positioning,remote sensing,non-contact temperaturemeasurement and many other fields.However,due to the relatively high power of infraredlight sources,the development of related infrared light source application technologies isrestricted.With the rapid development of integrated circuit technology in recent years,theperformance of electronic components such as microcontrollers and high-power field effecttransistors has been greatly improved,making the use of microcontrollers to control infraredlight sources a mainstream trend.This design uses the MSP430 MCU and the stabilizedvoltage to realize the voltage control of the infrared light source and the microcontrollertechnology to control the on and off of the field effect tube to realize the electronicmodulation of the infrared light source.Keywords:Infrared light source;modulation;voltage control;MSP430;
