MULTIVARIATE FLAW DETECTOR Russian patent published in 1998 - IPC

FIELD: ultrasound flaw detection, in particular, for testing quality of multilayer polymer composites. SUBSTANCE: device has ultrasound converter of sounding pulses, channel for receiving and processing of signal with respect to amplitude and delay time. In addition device has signal processing channel with respect to signal shape. It has interface unit comprised in serial circuit of analog-to-digital converter and code storage buffer, memory unit, calculation unit, visualization and graphic display system, as well read-only memory unit for storage of software libraries and reference signals and information input unit which are connected to calculation unit. EFFECT: increased validity and speed of flaw detection due to use of additional information characteristics of signal and automatic reading procedure. 4 dwg, 1 tbl
