VS method

Vibroscanning method
VS method is developed for measuring inner dimensions of smallholes. In VS method (with a single probe system,) the electrical contact between avibrating probe and the inner surface of a hole is detected and the duty factor of the contact ismeasured. Through controlled scanning by a probe with a constant duty factor, data on theups and downs of the surface profile are obtained. To characterize inside profiles ofmicro-holes regardless of materials, a twin-probe VS method (with electrical contact between a between probes) is developed.
