steradiancy
steradiancy noun: the rate of radiation transfer from a surface for each steradian of solid angle in a specified direction per unit area of cross section of the radiation perpendicular to that direction.
Noun
steradiancy (countable and uncountable, plural steradiancies)
- The rate of radiation transfer from a surface for each steradian of solid angle in a specified direction per unit area of cross section of the radiation perpendicular to that direction
- Such sources usually attain brilliance by high current densities in small volumes. The total energy output may therefore be less than a greatly extended source of low steradiancy.1954, Alexander Hollaender, Radiation Biology: Ultraviolet and related radiations, page 123
- The geometry of the cone θ and the irradiance at the image of the carbon block were used to determine the absolute steradiancy of the energy in the cone θ as a radiometer calibration value.1959, United States. National Aeronautics and Space Administration, NASA Technical Note (issues 3641-3650, page 15)
