"WebOct 5, 2024 · The BRDF is defined as radiance / irradiance in sr−1 s r − 1 unit. The power of the source is 1W. The surface of the detector equals the sample surface. So, the NSDD value must be divided by cosine of emergence angle to get the BRDF value. This will take in account the variation of apparent area of the sample viewed from the detector.
