摘要： A compact, bright and high-performance viewing optical system and an image display apparatus using the same. The viewing optical system uses an ocular optical system, which is formed from a decentered prism, and a reflection type image display device. The image display device has a light source and an illuminating light guide prism for guiding a light beam from the light source so that the light beam is applied to the display surface from the front side thereof. The ocular optical system includes a prism having an entrance surface through which a light beam reflected from the display surface enters the prism after passing through the illuminating light guide prism. The prism further has a reflecting surface and an exit surface through which the light beam exits from the prism. The reflecting surface is decentered with respect to the optical axis and has a rotationally asymmetric curved surface configuration that corrects decentration aberrations due to the decentration of the reflecting surface and gives a power to the light beam. The spacing between the entrance surface of the prism and the display surface satisfies a predetermined condition to lead the image to the pupil position.

In the second prism, an optical path crosses itself. At least one of the second and third surfaces has a rotationally asymmetric surface configuration that gives a power to a light beam and corrects aberrations due to decentration. The first prism has a reflecting surface, an entrance surface, and an exit surface. The reflecting surface has a rotationally asymmetric surface configuration that gives a power to a light beam and corrects aberrations due to decentration. An intermediate image surface is formed between the first surface of the first prism and the exit surface of the second prism.

摘要： An optical element is made of a transparent medium that is rotationally symmetric relative to the central axis with a refractive index greater than 1. The transparent medium has a first transmissive surface at the outermost periphery relative to the central axis, a first reflective surface at the side of the central axis relative to the first transmissive surface, a second reflective surface at the side opposite to the image plane relative to the first reflective surface and a second transmissive surface at the side of the image plane relative to the second reflective surface. The flux of light enters and proceeds through the transparent medium via the first transmissive surface, the first reflective surface, the second reflective surface and the second transmissive surface to form an optical path. The optical path is formed only at a side relative to the central axis.
