A novel measurement technique for visualizing the spatial temperature distribution of a non-isothermal gas flow has been developed. By tracking the movement path of a specifically-developed multi-sensor temperature probe using a commercially-available high-speed CCD camera, we can measure quantitatively a two-dimensional temperature profile and project it to the measurement object image obtained by the CCD camera. The key technique is an adaptive response-compensation scheme based on a "two-thermocouple probe technique," by which the response lag of the temperature sensors can be adequately compensated; hence the temperature profile can be reconstructed accurately. As an example, we have demonstrated that the temperature field of the hot-air jet ejected from a hair dryer can be visualized readily and quantitatively. The results show the effectiveness and usefulness of the proposed visualization technique.

提出了一种新的非等温气流空间温度分布的可视化测量技术。通过使用市售的高速CCD照相机跟踪专门开发的多传感器温度探头的移动路径，我们可以定量测量二维温度分布，并将其投影到由CCD照相机获得的测量对象图像上。其关键技术是一种基于“双热电偶探头技术”的自适应响应补偿方案，通过该方案可以充分补偿温度传感器的响应滞后，从而可以准确地重建温度分布。作为一个例子，我们已经证明，从吹风机喷出的热空气射流的温度场可以很容易地和定量地可视化。结果表明了所提出的可视化技术的有效性和实用性。
