SPATIALLY MODIFYING POLARIZATION STATE OF LIGHT |
摘要 |
Systems and methods configured for outputting light having a polarization state distribution that is spatially uniform by applying a correction to, for example, a beam of light with a spatially uniform polarization state distribution that has been altered (unintentionally or otherwise) to become spatially non-uniform are described. A projection system can include an optical element and a polarization-altering device (PAD). The optical element can cause a polarization of light in the projection system to be spatially non-uniform. The PAD can change the polarization state distribution of the light spatially based on an amount of spatial non-uniformity on the light caused by the optical element and before the light enters the optical element. The projection system can output the light having a spatially uniform polarization state distribution. |
