Abstract

The authors evaluate possible sensor solutions for radiometric imaging in the shortwave regime (0.2 - 2.5 µm), and simulate the spectral response to the AM 1.5 Standard Solar Spectrum [1] as well as the reflected response of this spectrum from various materials commonly found in the built environment. The authors show that only a thermopile sensor has satisfactory spectral response to yield accurate results for a range of materials and conditions. Following these, the authors demonstrate the construction of a 80x64 pixel thermopile array shortwave imaging system that can be used to generate 360 degree spherical panoramas of the shortwave radiance in W/m2. These data are then combined with novel analysis methods to generate simulated pyranometer readings that are validated against reference pyranometer data. Additionally, these data are then combined with matching radiant panoramas of the longwave (5 to 30 µm) thermal regime to facilitate further analysis and insights.
