Abstract

FIELD: representation of spatial distribution of temperature of examined region of various objects; can be used, for example, in medical diagnosis, in industry for control of temperature inside massive parts, etc, as well as for flaw detection of various materials. SUBSTANCE: the device for representation uses m receiving channels, each consisting of series-connected signal transducer, amplifier, analog-to-digital converter and storage unit, correlation processor with m inputs consisting of series-connected multiplier and integrator and coupled to the outputs of the receiving channels, logger connected to the output of the correlation processor, control unit and signal delay computing unit. The control unit controls triggering of the analog- to-digital converters and defines the coordinates of the points of the examined region of the object to the signal delay computing unit and to the logger. The signal delay computing unit transmits the computed signals to the control inputs of the storage units of the receiving channels. EFFECT: the given device provides for a pattern of continuous spatial distribution of radiation sources in two-dimensional and three- dimensional space, ensuring a good resolving power. 34 cl, 7 dwg

Изобретение может быть использовано для отображения пространственного распределения температуры исследуемой области различных объектов и применятся, например, в медицинской диагностике, в промышленности для контроля температуры внутри массивных деталей и т.д., а также для дефектоскопии различных материалов. Устройство отображения содержит m приемных каналов, каждый из которых состоит из последовательного соединенных преобразователя сигналов, усилителя, аналого-цифрового преобразователя и блока памяти, корреляционный процессор с m входами, состоящий из последовательно соединенных перемножителя и интегратора и связанный с выходами приемных каналов, регистрирующее устройство, соединенное с выходом корреляционного процессора, блок управления и блок вычисления задержек сигналов. Блок управления управляет запуском аналого-цифровых преобразователей и задаст координаты точек исследуемой области объекта в блок вычисления задержек сигналов и в регистрирующее устройство. Блок вычисления задержек сигналов подает рассчитанные сигналы на управляющие входы блоков памяти приемных каналов. Устройство позволяет получить картину непрерывного пространственного распределения источников излучения в двумерном и трехмерном пространстве, обеспечивая достаточно хорошее разрешение.The invention can be used to display the spatial temperature distribution of the studied area of various objects and is used, for example, in medical diagnostics, in industry to control the temperature inside massive parts, etc., as well as for flaw detection of various materials. The display device contains m receiving channels, each of which consists of a series-connected signal converter, amplifier, analog-to-digital converter and a memory unit, a correlation processor with m inputs, consisting of series-connected multiplier and integrator and connected to the outputs of the receiving channels, a recording device, connected to the output of the correlation processor, a control unit and a signal delay calculation unit. The control unit controls the start of analog-to-digital converters and sets the coordinates of the points of the studied area of the object in the block for calculating signal delays and in the recording device. The signal delay calculation unit provides the calculated signals to the control inputs of the receiving channel memory units. The device allows you to get a picture of the continuous spatial distribution of radiation sources in two-dimensional and three-dimensional space, providing a fairly good resolution.
