摘要: 为了解决非接触测温系统中常见的成本高昂、系统复杂、实用性差、响应速度慢等问题，采用多光谱测温和快速响应光电探测技术，设计了一套低成本高速多光谱辐射测温系统。利用高速微弱光信号采集模块、高速模数转换芯片、高性能可编程门阵列和同步动态随机存取内存保证了微弱光信号的高速转换、同步采集、大容量缓存，具备纳秒级变化温度场的测量能力。结果表明，测温误差小于±1%, 时间分辨率可达到50ns。这一结果对于快速变化温度场的测量是有帮助的。Abstract: In order to solve the problems of high cost, complex system, poor practicability, and slow response speed in common non-contact temperature measurement systems, multi-spectral temperature measurement and fast-response photoelectric detection technology were adopted, and a low-cost and high-speed multi-spectral radiation temperature measurement system was designed. By using the high-speed weak optical signal acquisition module, high-speed analog-to-digital conversion chip, high-performance field-programmable gate array, and synchronous dynamic random-access memory, ensures the high-speed conversion, synchronous acquisition, large-capacity buffering of weak optical signals and the ability to measure temperature field changes in nanoseconds can be obtained. The results show that, temperature measurement error is less than ±1% and time resolution can reach 50ns. This result is helpful for the measurement of rapidly changing temperature field.
