Lambertian intensity distribution

TīmeklisLike intensity, radiance can vary with the direction from the object to the observer. (An object that has constant radiance over all directions is called lambertian. A very matte piece of paper and the surface of a fluorescent light tube are good approximations of lambertian objects.) Figure 2. Tīmeklis2024. gada 11. apr. · The intensity of fluorescence increased with increasing concentration. Moreover, the concentration of Bi 3+ ions within a certain range can be quantitatively analyzed by a calibration curve. By adding different ions to the sensor, the stronger emission intensity resulted in a great selectivity for Bi 3+ ions in the co …
