Abstract
Abstract An optical system for superimposing images on a single image plane from both directional and non-directional sources is disclosed. An apertured mirror is placed at an angle to a source of a diffused light image, to reflect light therefrom toward an image plane, such as a display screen or photosensitive sheet. A second, directional image is projected by an optical system through the aperture toward the image plane. A single objective lens assembly placed between the mirror and the image plane acts on light rays from both sources producing both images in superimposition in the image plane.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
115 words
An optical system comprising: a. a first imaging means including a substantially planar diffuse, non-directional, light-and-shadow image source; b. an apertured reflecting surface positioned at an angle to the plane of said first image source to reflect light emitted thereby said reflecting surface being substantially totally reflecting; c. a lens system positioned to receive light reflected by said apertured reflecting surface and to form an image therefrom on an image plane; and d. a second imaging means positioned to project light from a directional image source through the aperture in said apertured reflecting surface, and through said lens system to form a second image in superimposed register with said first image on said image plane.
Claim 2
Dependent Claim
115 words
An optical system comprising: a. a first imaging means including a substantially planar diffuse, non-directional, light-and-shadow image source; b. an apertured reflecting surface positioned at an angle to the plane of said first image source to reflect light emitted thereby said reflecting surface being substantially totally reflecting; c. a lens system positioned to receive light reflected by said apertured reflecting surface and to form an image therefrom on an image plane; and d. a second imaging means positioned to project light from a directional image source through the aperture in said apertured reflecting surface, and through said lens system to form a second image in superimposed register with said first image on said image plane.
Claim 3
Dependent Claim
37 words
The optical system according to claim 1 wherein said first imaging means includes a caThode ray tube screen, said second imaging means includes a transparency projection system and said image plane includes a sheet of photosensitive material.
Claim 4
Dependent Claim
35 words
The optical system according to claim 2 wherein said aperture has a size just sufficient to pass the significant portion of the zero order diffraction pattern of the transparency used in said transparency projection system.
Claim 5
Dependent Claim
142 words
An optical system comprising: a. first and second spaced imaging means, each including a substantially planar, diffuse, non-directional, light-and-shadow image source; b. a first apertured substantially totally reflecting surface arranged at an angle to the plane of said first image source to reflect light emitted thereby along an optical axis; c. a second apertured substantially totally reflecting surface positioned within the aperture in said first reflecting surface, arranged at an angle to the plane of said second image source to reflect light emitted thereby along said optical axis; d. a third imaging means positioned to project light from a directional image source through the aperture in said second apertured reflecting surface along said optical axis; and e. a lens system positioned along said optical axis receiving light from each imaging means to form images in superimposed register in a single image plane.
Claim 6
Dependent Claim
142 words
