ELECTRONIC CONTROL AND AMPLIFICATION DEVICE FOR A PIEZOELECTRIC LOCAL PROBE FOR MEASURING FORCE BENEATH A PARTICLE BEAM |
摘要 |
<p>An electronic control device for a local probe with a piezoelectric resonator and preamplification and processing of its signals, the probe being configured for local measurement of physical properties of a sample in an environment with a particle beam directed towards the probe, in which an excitation voltage generated by an excitation mechanism is applied to the piezoelectric resonator through a first galvanic isolation transformer, and a current for measurement of mechanical oscillations of the piezoelectric resonator is applied through a second galvanic isolation transformer to a preamplification device on the output side.</p> |
