FIELD: display of spatial temperature distribution in medical diagnostics and in industry to control temperature inside solid parts, etc; flaw inspection of various materials. SUBSTANCE: device has m receiving channels each incorporating series-connected signal converter, amplifier, analog-to-digital converter, and storage unit, m-input correlation processor built up of series-connected multiplier and integrator and coupled with outputs of receiving channels, recording device connected to correlation processor output, control unit, and signal delay computing unit. Analog-to-digital converter starting control unit specifies coordinates of analyzed region points for signal delay computing unit and recording device. Signal delay computing unit passes computer signals to control inputs of storage units in receiving channels. EFFECT: enlarged functional capabilities. 4 cl, 7 dwg
