| Popis: | Optical designs for three-panel LCoS projection systems are reviewed. The impact of polarization aberrations in prism-based systems is discussed and a simple model to analyze the sensitivity of contrast to thermal gradients in prisms is presented. To eliminate stress birefringence in LCoS projection systems, we have developed a projection optical system that does not require the use of polarizing prisms. An improved off-axis design has been designed that simplifies manufacture and reduces cost. The performance of systems based on this architecture will be discussed. |
