The Measurement and Simulation of the Light of the Night Sky

摘要

A description is given of the spectral distribution and origins of the light of the night sky. Details are provided of the design of a filter for use with a tungsten filament light source to produce a spectral distribution similar to that of the moonless night sky. The level of illumination from the filtered light source was set by reference to radiometer measurements of the night sky made at a remote coastal location. (Author)
