METHOD AND DEVICE FOR ACOUSTIC TESTING OF OBJECTS Russian patent published in 2009 - IPC G01N29/24 

FIELD: instrument making.

SUBSTANCE: proposed invention is intended for acoustic resting of an object. The essence of the invention consists in that, at least, during one moment of testing ultrasound signal (S1, S2) is sent into test object (2). Note here that after expiration of test preset period (Δt₁, Δt₂), measured from each moment of testing and ultrasound signal (S1', S2') into aforesaid object (2). Possible echo-signal from signal (S1, S2) is received from object (2) at appropriate fist moment of measurement. Note here that aforesaid possible echo-signal is taken to be echo-signal (E1, E2) of signal (S1, S2) only provided that echo-signal (E1', E2') of ultrasound signal (S1', S2') is received at appropriate second moment of testing.

EFFECT: higher accuracy of testing.
