The oblique projection optical system has, in the order from a reduction side: a refraction optical portion having a positive optical power, a concave reflection surface having a positive optical power, and a convex reflection surface having a negative optical power. The refraction optical portion includes a rotationally symmetric coaxial refraction group. An intermediate image of the image formed on the display device surface is formed between the refraction optical portion and the concave reflection surface.

    摘要： A catadioptric projection objective for imaging an off-axis effective object field arranged in an object surface of the projection objective onto an off-axis effective image field arranged in an image surface of the projection objective has: an optical axis; an effective object field situated entirely outside the optical axis and having a length A in a first direction and a width B in a second direction perpendicular to the first direction such that a circular area of minimum size enclosing the effective object field defines a radius REOF of the effective object field according to: R EOF = ( A / 2 ) 2 + ( B / 2 ) 2 ; and a circular design object field centered around the optical axis having a design object field radius RDOF, where the projection objective is essentially corrected with respect to image aberrations in zones having radial coordinates smaller than RDOF and wherein the projection objective is not fully corrected in zones having radial coordinates larger than RDOF. The conditions: RDOF=γ REOF and 1≦γ 1 are possible with a compact design. Arcuate effective object fields are preferably used.

    摘要： An extremely compact prism optical element, image observation apparatus and image display apparatus which are capable of providing an observation image that is clear and has minimal aberration and minimal distortion even at a wide field angle. Light rays emitted from an image display device (7) enter an ocular optical system (12) through a fourth surface (6) and are totally reflected toward an observer's pupil (1) by a third surface (5). The reflected light rays are reflected by a first surface (3) disposed immediately in front of the observer's pupil (1) and then reflected toward the observer's pupil (1) by a second surface (4). The reflected light rays pass through the first surface (3) and are projected into an observer's eyeball (15) with the observer's iris position as an exit pupil (1). When an external-scene image is observed, light rays from an object point in,the external scene enter the ocular optical system (12) through the third surface (5), pass through the first surface (3) and are projected into the observer's eyeball (15). Assuming that the angle of internal reflection of an arbitrary light ray at the third surface (5) is nullr3, the ocular optical system (12) satisfies the condition of sinnull1(1/nd)nullnullr3null60null, where nd is the refractive index for the spectral d-line of the medium of the ocular optical system (12).
