Contactless measurement correlator of relative speed of object - uses two measuring sensors in movement direction of object or measuring appts.

摘要

Contactless measurement correlator fo relative speed of object has two measuring sensors in tandem in movement direction of object or measuring apparatus. The measuring sensors generate signals which are out of phase by the transit time corresponding to the physical structure of the object. With the aid of limiters of a shift register a signal is obtained from the first signals for setting a model transit time, a differentiation element and logical conectors. This signal is passed to an integral regulator the output signal of which adjusts the transit time of the shift register by means of a clock frequency.
