摘　　要：构建了投影机光路系统通用框图,以光源组件、光分离组件、成像器件等对光效率影响较大的部件为例,对常用投影机光效率做了比较研究,为客观评价不同投影机光效率提供了依据。A general block diagram of the projector optical system is built.Taking these components such as the light source package,separate package,imaging devices,etc.as examples,the comparison of optical efficiency of several projectors is made,which provides the bases for objectively evaluating the optical efficiency for different projectors.

关 键 词：投影机 光效率 比较研究
