Paper Abstract

Fiber optical Sagnac interferometer is applied for absolute calibration of ultrasonic pulsed source. Method of topological phase is used for the maintenance of &pgr;/2 phase bias of the counterpropagating waves. Non-disturbing absolute measurement of the ultrasonic displacement with sensitivity of 10-1 Å within 100 kHz ÷ 30 MHz band is demonstrated which is comparable with more complicated and expensive analogs.
