摘要
研制了X波段在体剂量检测专用EPR谱仪的数据采集与控制系统,利用阿尔泰USB2812数据采集卡作为控制卡,在LabVIEW图形化编程开发环境中进行程序开发,实现了扫场电源的控制、微波模的显示、微波功率的控制和EPR信号的采集等功能.数据处理程序可实现存储数据的查询、谱线基线校正和积分等基本功能,为下一步开展牙齿剂量试验研究提供了平台.
An EPR data acquisition and control system for in vivo tooth dosimetry was developed. Based on the graphical programming language, LabVIEW and using the ART USB2812 data acquisition card as the controller card, the system can perform the basic functions of EPR. controlling the power of the scanning field, displaying the microwave mode signal, adjusting the microwave power, and acquiring EPR signals. The data processing program developed has basic spectrum processing functions, data query, spectral baseline correction and integration.
