穆斯堡尔谱仪驱动电路的功能,是产生一个驱动电压来推动振动子,使之按要求的速度波形运动。穆斯堡尔谱仪的机电振动装置采用扬声器系统。它具有线性的电能-机械能转换特性。根据振动子的质量,弹性系数及线圈的阻抗,可以精确计算出驱动电压的波形和大小。通常并不需要专门装配驱动电压发生器,而是用一个参考波形发生器和一个负反馈放大电路来实现。当负反馈放大倍数足够大时,反馈系统自己就可以产生所要求的驱动电压。
The function of a Mössbauer spectrometer drive circuit is to generate a drive voltage that drives the vibrator to move at the required speed waveform. Matsbauer spectrometer mechanical and electrical vibration using speaker system. It has a linear electrical energy - mechanical energy conversion characteristics. According to the quality of the vibrator, the spring constant and the impedance of the coil, the waveform and size of the driving voltage can be precisely calculated. Usually do not need to specially assemble the drive voltage generator, but with a reference waveform generator and a negative feedback amplifier circuit to achieve. When the negative feedback amplification is large enough, the feedback system itself can produce the required driving voltage.
