Theoretical Simulation for Evaluating Error in Irradiance Measurement Using Optical Detectors Having Different Cosine Responses

Cosine response is an important characteristic of optical detector for irradiance measurements. The non-ideal cosine a may lead to errors in In this paper, theoretical simulation generated due isotropic point light sources carried out different illumination conditions. Simulation results show that the measurements error detectors become significantly high at edges and corners floor when source placed center roof. Further, it observed are more enclosures having height smaller than dimensions. Even calibrated measure erratic values wider angle incidence. Therefore, great importance especially during current scenarios COVID-19 pandemic, ensuring correct dose Ultraviolet Germicidal Irradiation (UVGI).
