Paper Abstract

We validate the S-S method and the differential operator method through numerical simulations and experiments. Using a LED with a bandwidth of about 10nm as light source, we measure the spectral irradiance of the LED when the spectroradiometer bandwidth is 1nm and 5nm. The S-S method and the differential operator method act on experimental results to identify the efficiency of the methods. Through our analysis, the correction methods play significant roles in the spectral irradiance measurement. Especially, the correction methods are necessary when the light source has a narrow bandwidth feature.
