摘要： A plurality of first cylindrical lenses aligned in an array, having a collecting function with respect to an alignment direction parallel to the array, to collect luminous flux from a body to be imaged. A first reflective collector-surface having a reflective collecting function with respect to a perpendicular direction perpendicular to the alignment direction collects the luminous flux from the plurality of first cylindrical lenses, and provides a collected parallel luminous flux to a plurality of roof-mirror type reflective plane-pairs or to a plurality of right-angle prisms. The plurality of roof-mirror type reflective plane-pairs or right-angle prisms reflects the luminous flux toward a second reflective collector-surface disposed for convergence of the luminous flux with respect to the perpendicular direction. The second reflective collector-surface reflects the luminous flux toward a plurality of second cylindrical lenses disposed for convergence of the luminous flux with respect to the alignment direction. Further, the luminous flux from the plurality of second cylindrical lenses converges to form an image.

摘要： A polarization conversion element having plural polarization separation sections and plural phase modulation sections is disclosed. A light flux is separated into transmission light (P polarization) and reflection light (S polarization) by being input to a polarization separation section. The reflection light reflected at the polarization separation section is output in the same direction as that of the transmission light by being reflected again at an adjacent polarization separation section at a different position from a position where a light flux is input to the adjacent polarization separation section. The phase modulation section is disposed on an optical path of the transmission light or the reflection light and output light becomes the same polarization.
