| Résumé : |
Integrating spheres collect and spatially integrate radiant flux. The flux can be measured directly or after it has interacted with a material sample. The sphere as part of a radiometer or photometer can directly measure the flux originating from lamps and lasers or the flux density produced from hemispherical illumination. Perhaps the largest application for integrating spheres is in the measurement of the total reflectance or transmittance from diffuse or scattering materials. An alternative application utilizes the port opening of an internally illuminated integrating sphere as a large area source that features uniform radiance. Theses sources can be used to calibrate electronic imaging devices and systems or simply as uniform back illuminators. |
