fényvisszaverképességének
Fényvisszaverképességének, often abbreviated as FVK, is a measure used in optics and photography to quantify the ability of a lens or optical system to return light back to its source. This property is crucial for applications where the direction of light is critical, such as in laser systems, optical communication, and certain types of imaging.
The FVK is typically expressed as a percentage and is defined as the ratio of the light
There are several factors that influence the FVK of an optical system, including the surface roughness, the
In photography, a high FVK is desirable as it can help reduce flare, which is the effect
The FVK is an important parameter in the design and evaluation of optical systems, as it directly
