Optical sphere
An integrating sphere (also known as an Ulbricht sphere) is an optical component consisting of a hollow spherical cavity with its interior covered with a diffuse white reflective coating, with small holes for entrance and exit ports. Its relevant property is a uniform scattering or diffusing effect. Light rays incident on any point on the inner surface are, by multiple scattering reflections, distribute… Webthe light reflected from the sphere–medium interface and that traveling a round-trip optical path through the center of the sphere. If our hypothesis is valid, the frequency and peak …
