摘要： A projection optical apparatus capable of providing high image quality and having a reduced size. The projection optical apparatus comprises a light valve and a projection optical system including a first optical system (5) having a transmissive-refractive element and a second optical system (3′) having a reflective-refractive element. An image formed on the light valve is projected by the projection optical system on a projection surface (4). The optical axis in the first optical system (5) is folded both vertically and horizontally. The first group (5A) of the first optical system is contained in a space (dead space) whose lower limit is defined by a lower edge of the second optical system (3′)/thereby reducing the depth of the apparatus.

摘要： A projection optical system includes first and second optical systems. The first optical system includes a transmissive-refractive element and the second optical system includes a reflective-refractive element. An image formed by a spatial light modulator is projected by the projection optical system on a projection surface. A light beam that travels along an optical path that leads from the second optical system to the projection surface in an optical path between a center of the image formed by the spatial light modulator and the projection surface is projected at an angle with respect to a normal to the projection surface. An optical axis of the first optical system is folded to a folded position by an optical path deflecting unit in an area of the first optical system where the light beam entering the optical path deflecting unit is a converging light beam or a substantially parallel light beam.
