Abstract
|
|
|
|
| The reflected apparent temperature is an important factor for performing accurate IR temperature measurements. In this paper, the influence of hot spots on this reflected apparent temperature was investigated for a diffuse versus specular reflector. Two different sizes of hot spots were used, representing a drone battery and an operator. The results were illustrated by IR object temperature readings on two materials (glass and frosted glass) with similar emissivity yet specular versus diffuse reflective characteristics. The results show that hot spots should be avoided at all times, with extra attention when performing spot measurements on short distances and on specular surfaces. |
