Abstract

PURPOSE:To perform measurement with less errors by measuring the spectral distribution of a light source simultaneously with the measurement of radiation illuminance distribution thereby correcting the cosine characteristics of photo detectors and correcting the measurement errors owing to the non-conicidence of the spectral sensitivities among the photo detectors.
