Abstract

Temperature measurement plays a vital role in industrial production, scientific research, and daily life. Traditional contact temperature measurement methods face limitations such as restricted measurement range and probe aging in extreme environments. Contact temperature measurement techniques offer high accuracy, fast response, and strong adaptability, but still encounter challenges such as the uncertain emissivity of high-temperature objects and interference from environmental reflections. This paper systematically reviews the fundamental principles of optical temperature measurement, categorizes its methods, and elaborates on the principles, characteristics, and applications of radiation thermometry and fiber-optic temperature measurement. Case studies, including molten steel casting temperature monitoring, gas turbine blade temperature measurement, and natural gas tank inspection, are analyzed to explore the applicable scenarios, advantages, and disadvantages of different optical methods. Optical temperature measurement enables non-contact, real-time, and long-distance temperature sensing, making it highly promising for applications in industrial high-temperature monitoring and energy pipeline inspection. Research shows that combining optical techniques with traditional methods, optimizing optical system design, and introducing advanced signal processing technologies can enhance measurement accuracy and expand their applicability in complex environments.
