Polarizing filter (photography) - Wikipedia

There are two types of polarizing filters readily available, linear and circular, which have exactly the same effect photographically. But the metering and auto-focus sensors in certain cameras, including virtually all auto-focus single-lens reflex cameras (SLRs), will not work properly with linear polarizers because the beam splitters used to split off the light for focusing and metering are polarization-dependent. Linearly-polarized light may also defeat the action of the anti-aliasing filter (low … WebFirst, in the region proposal stage, a circular intensity filter, which is designed based on the characteristics of the aircraft target, can quickly locate the centers of multi-scale suspicious... phonak target download free
