Photometers are widely used for the measurement of the average LED intensity as defined by CIE 127, under the circumstance that LEDs have many kinds of intensity spatial distributions. Significant measurement errors can be resulted due to the followi

In spectral radiation detection, spectral characteristics of the environment are completely different from standard light sources, so the output characteristics of optical imaging device is bound to bring greater error due to spectrum matching in ima

A night-sky luminance survey was carried on in Beijing to assess the level of light pollution. The luminance of the zenith night sky and skies in four directions at six sites with different distances from the city center was measured by using a photo
