摘要
正电子湮灭技术是固体材料电子结构和缺陷的敏感探针,在凝聚态物理、材料科学等领域有着特殊的作用。多普勒展宽谱以及寿命谱能提供固体电子动量分布、密度分布以及缺陷类型的信息。基于正电子湮灭技术的双通道多普勒仪是近十年来发展起来的新技术,能够获得很多电子信息。
本论文针对双通道正电子多普勒谱仪信号处理显示系统开展研究,完成数据采集电路以及基于QT的人际交互界面的设计等。基于正电子湮灭技术研制的多普勒谱仪信号处理显示系统完成数据的模数转换、判断筛选、数据传输、算法分析以及数据图形显示等功能。
在硬件设计方面,完成了电路设计和版图设计。其中主要包括数据采集AD、网络传输以及电源模块的设计。基于QT的上层软件设计,实现人机交互界面和数据处理以及算法分析等功能。系统根据工作模式的不同,完成在波形模式、多道模式、多普勒模式以及AMOC模式下的数据滤波、处理、以及图形显示等。同时,还完成多普勒工作模式下和AMOC工作模式下的数据算法分析,得到可靠的和谱、差谱等分析结果。
在此基础上,将系统用于谱仪当中并对一系列样品进行检测和分析,结果验证了系统的可靠性和可行性。最后得出了主要的结论。
Positron Annihilation Technique is a sensitive probe to the electronic structure and defects of the solid materials, and it plays a special role in condensed matter physics, materials science and other fields. Doppler-broadening spectrum effect and lifetime spectrum can provide the information of the electronic momentum distribution、density distribution and the defect type. The dual-channel Doppler technology based on Positron Annihilation Technique is developed as a new technology over the past decade, which can achieve much electronic information.
This dissertation is aimed at the signal processing and display system of dual-channel positron Doppler spectrometer, and completes the design of the data acquisition circuit, the upper QT-based man-machine interface and so on. The signal processing and display system of the Doppler spectrometer based on the Positron Annihilation Technique accomplishes the analog-digital conversion, estimation and filter, data transmission, algorithm analysis, graphical display etc.
In the respect of hardware design, the circuit design and layout are fulfilled. The data acquisition AD module, network transmission module and power module are mainly included. The upper QT-based software accomplishes these functions of man-machine interface, data processing, and algorithm analysis. According to the different work patterns of the waveform mode, multi-channel mode, Doppler mode and AMOC mode, the system actualizes the data filter, processing and graphical display. In addition, the data algorithm analysis in the Doppler and AMOC modes is finished, and the reliable results of sum spectrum and sub spectrum are carried out.
Based on these, the system is used in the spectrometer and a series of samples are measured and analyzed. The results verify the reliability and feasibility of the system. At the end, the main conclusions are summarized.
