| Abstract: | Based on the Kirchhoff law, according to the relationships between various technical parameters and main specifications (temperature resolving power, temperature measurement sensitivity, relative temperature measurement sensitivity, and temperature measurement accuracy), an optimal method of the practical real-time temperature measurement system using laser diode and LiTaO3 pyroelectric detector is proposed. Experimental results show that temperature measurement accuracy is suitable for our requirement in the range of 400~1200℃. |
| Keywords: | Temperature measurement by radiation Pyroelectric detector Temperature resolving power Temperature measurement sensitivity Temperature measurement accuracy Laser diode |
