摘要： The present invention relates to an image display apparatus, e.g. a head-mounted image display apparatus, in which an image from a single image display device is led to two eyes without using a half-mirror, thereby allowing observation of a bright image. The image display apparatus has an optical path distributing mirror 1 for distributing the image of a single display device 10 to an optical path for a right eye and an optical path for a left eye, and an ocular prism 2R for the right eye and an ocular prism 2L for the left eye, which are placed on the right- and left-hand sides, respectively, of the optical path distributing mirror 1. In the optical path for the right eye, display light from the display device 3 is reflected by a reflecting surface 1R of the optical path distributing mirror 1 and passes through a first surface 21R of the decentered prism member 2R to enter the prism, in which the light is totally reflected by a second surface 22R, which serves also as a fourth surface 24R, and back-reflected by a third surface 23R to exit from the prism through the fourth surface 24R. The light is led to an exit pupil 4R for the right eye to project an enlarged image of the display device 3 into the right eye. The same is true in the optical path for the left eye.

摘要： An image display apparatus allows an image from a single image display device to be led to two eyes without using a half-mirror, thereby allowing observation of a bright image, and facilitates correction of various aberrations. A viewing optical system includes a left ocular part, a right ocular part, and an optical path distributing part for leading a light beam from a single image display device to the left and right ocular parts. The left and right ocular parts each have at least two reflecting surfaces. The optical path distributing part has at least one pair of reflecting surfaces for left and right optical paths. These reflecting surfaces are formed from rotationally asymmetric curved reflecting surfaces having the function of correcting decentration aberrations. The left and right optical paths of the viewing optical system are formed by optical surfaces arranged so that the left and right optical paths are not in plane symmetry with each other but in 180-degree rotational symmetry with respect to only a normal line passing through the center of the image display device.

摘要： An image display apparatus having a three-dimensionally decentered optical path to attain a reduction in overall size of the apparatus and to place constituent members effectively in a dead space, thereby permitting the apparatus to be designed in a variety of ways. The apparatus includes an image display device and a viewing optical system for leading an image formed by the image display device to a pupil. The viewing optical system has at least a first reflecting surface and a second reflecting surface positioned closer to the pupil than the first reflecting surface along the optical path. A first plane defined by the optical axis incident on the first reflecting surface and the optical axis reflected therefrom and a second plane defined by the optical axis incident on the second reflecting surface and the optical axis reflected therefrom intersect each other at an arbitrary angle, thereby forming a three-dimensionally decentered optical path. At least either one of the first and second reflecting surfaces has a curved surface configuration.

摘要： A viewing optical system and an image-forming optical system, in which an intermediate image is formed once and two decentered prisms, i.e. first and second prisms, are arranged to correct each other's decentration aberrations, thereby attaining a wide viewing field angle and a short focal length. The second prism is placed closer to the image side than the first prism and has four optical surfaces, of which a first surface is an entrance surface, second and third surfaces are reflecting surfaces, and a fourth surface is an exit surface. 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.
