| 摘要 |
This invention discloses an imaging system, including a light source, a polarizing beam splitter (PBS) operative to split light impinging thereon from the light source into two generally linearly polarized beams, a pair of optical elements through which pass the linearly polarized beams, the optical elements being operative to change the linearly polarized beams into generally circularly polarized beams, and for each beam, a spatial light modulator (SLM) operative to selectively reflect the generally circularly polarized beam back towards the optical element, the optical element changing the circularly polarized beam into a generally linearly polarized beam with its polarity rotated at an angle to the first-mentioned linearly polarized beam. |
