Simultaneous comparison of thermal radiation energy in vertical and horizontal directions using a surface mirror

− A simple comparison method for surface vapor deposition mirror sheets−

Abstract

The recent heat environment is so severe as we want to measure that heat environment simply and accurately. A study was conducted on the use of a reflector to enable comparison of thermal images for four directions taken at the same time by a surface mirror on a single image. A simple method of measuring emissivity was described using the instruments to measure radiant temperature. The use of multi-directional thermal radiation reflecting mirrors and their usefulness were discussed. The reflectance of reflective sheets recently acquired was found to be lower than that of the past, and even relatively thick film-based ones showed peripheral warping and lacked uniformity. The sheet based on glass showed lower distortion. However, glass-cutting techniques are required to process them into small pieces. Therefore, the Committee planned to insert small pieces of film-based commercial products into the present proceedings. We would like to find the opinions of the academic society members on its use and contribute to further usage and check for simple accuracy.
