Sphere-Spectroradiometry: Spectral Flux Evaluation

摘要

In spectroradiometer-sphere, total spectral radiant flux (Φ_e(λ)) of standard source is used to derive different photometric and colorimetric quantities. In general, Φ_e(λ) is measured using gonio-spectroradiometer, an expensive facility. In the present work, we proposed a convenient way to derive Φ_e(λ) form normalized spectral density of standard luminous flux lamp using spectroradiometer.
