摘要：

In projectors employing reflective liquid crystal light valves, polarizing beam splitters (PBS) have to be used. However, ordinary wide bandwidth PBSs have relatively small acceptance angles. This reduces the optical efficiency of the projectors. In this paper we present new designs for the PBS which has the advantage of large acceptance angles without compromising the operating bandwidth.
