Electronic adjustable color filter device |
摘要 |
An electronically adjustable, combinational color filter device is provided for generating color light. Incoming light is split in a polarizing beam splitter/combiner into a first and a second element of light. One or more wave plates operate to modify the polarization state of the first element of light, and one or more dichroic reflective filters reflect portions of the first element of light having a predetermined wavelength. Similarly, one or more wave plates operate to modify the polarization state of the second element of light, and one or more dichroic reflective filters reflect portions of the second element of light having a predetermined wavelength. Reflected portions of the first element and the second elements of light are combined in the polarizing beam splitter/combiner to create color light. A spatial light modulator may be used to create color images.
