Basic Theories About Goniophotometer Part3: Spatial Luminance Distribution and Spatial Spectral Distribution
Spatial Luminance Distribution and Near-field Goniophotometer The spatial luminance distribution and the size of emitting area different directions are important quantities, especially for the glare performance estimation. The imaging luminance meter based on CCDs receives the light from the source directly, and measure the luminance (luminance meter) of every point in the emitting area as [...]
