摘要

在这项工作中，我们设计并构建了两种类型的校准装置来研究不同条件下氧化铟锡薄膜热电偶的动态特性。第一个装置基于纳秒激光器，在25 ns内产生150-mW的热脉冲，冷却过程的实验分析揭示了自然对流条件下ITO TFTCs的动态特性。第二个装置使用爆震波，以4.86马赫的速度在400 ns内产生$270~^{\circ}$ C的气流环境，代表强制对流条件。实验结果表明，在纳秒激光实验中，ITO TFTC的时间常数为$122.08~\mu $ s，对应的频率响应为1.30 kHz。相比之下，在爆震波实验中，ITO TFTCs的时间常数降低到$15.65~\mu $ s，频率响应增加到10.17 kHz。这些结果表明，ITO TFTCs的动态特性不是恒定的，并且会受到测量环境的显著影响。

Microsecond Dynamic Response Calibration of ITO Thin-Film Thermocouples Under Laser and Detonation Conditions

In this work, we designed and built two types of calibration devices to study the dynamic characteristics of the indium tin oxide (ITO) thin-film thermocouples (TFTCs) under different conditions. The first device, based on a nanosecond laser, generates a 150-mW heat pulse within 25 ns, and the experimental analysis of the cooling process reveals the dynamic characteristics of the ITO TFTCs under natural convection conditions. The second device uses a detonation wave that generates a

$270~^{\circ }$

C airflow environment in 400 ns at 4.86 Mach, representing forced convection conditions. Experimental results show that in the nanosecond laser experiment, the time constant of the ITO TFTC is

$122.08~\mu $

s, corresponding to a frequency response of 1.30 kHz. In contrast, in the detonation wave experiment, the time constant of the ITO TFTCs decreases to

$15.65~\mu $

s and the frequency response increase to 10.17 kHz. These results demonstrate that the dynamic characteristics of the ITO TFTCs are not constant and can be significantly influenced by the measurement environment.
