ABSTRACT:
A minute change detecting system comprises sensor means which changes its electrical constant according to a physical change of an object under measurement to affect the oscillation frequency of at least one of two high-frequency oscillators, and mixer means for producing a beat frequency signal from the output oscillation frequencies of the two oscillators, thereby to detect the physical change.
