Abstract

PURPOSE: Detection accuracy is enhanced and the indication of the detection measurable range of a detecting oscillator is also made possible by detecting the frequency differences between the detecting oscillator and a reference oscillator in measuring the thicknesses of the film deposited on crystal vibrators.
