基于Labview的核磁共振磁场测量仪的研究

AN APPROACH TO A VIRTUAL NMR MAGNETOMETER BASED ON LABVIEW

核磁共振方法测量磁场是较精确的一种测量磁场的方法,由于在低磁场强度时共振信号相对于噪声很弱,给正确测出磁场造成困难.计算机虚拟仪器技术是先进的计算机测控技术,与核磁共振探头结合起来组成虚拟磁场测量仪,利用虚拟仪器软件Labview的强大功能,可以有效消除噪声的影响,并且结构简单实用.

<Abstrcat>Virtual Instrument technic has strong functions, it uses software instead of major parts of traditional hardware to configure high performance instruments; A NMR Magnetometer based on the software Labview for virtual instruments is introduced, the software successfully eliminates noise, detects NMR signal and measures magnetic field strength of 300Gs.
