A beam waveguide for guiding optical wave energy over extended distances by means of lenses of variable spacing whose focal lengths are a function of the separation from adjacent lenses and the maximum lens-to-lens spacing in the system.

The present invention relates to the formation of images by self-imaging through the use of an optical tunnel. An optical tunnel is provided which has dimensions defined so as to satisfy a criterion for the production of self-imaging of an object located along its optical axis. The object in the preferred embodiment is located in an object plane at one end of the optical tunnel and is illuminated by means of a monochromatic light source. In the object plane, outside of the optically denser mediu...

An optical substrate guided relay (300) includes a light homogenizing device (321) coupled to an optical input device (301) in an offset orientation along a first interface (331). The light homogenizing device (321) receives light from an image-producing source (804), which can be a scanned beam source, and creates multiple copies of the received light by way of a light homogenizing device (321). The light and copies are delivered to the optical input device (301). An optical substrate (302) rec...

A light pipe array includes a series of light pipes connected to a runner. The light pipes and runner are preferably molded as a single piece using a clear or transparent plastic. The runner is fabricated to have a relatively small cross-section when compared to the light pipes. The interconnection between the runner and each light pipe is chosen so that each light pipe is oriented to be substantially perpendicular to the runner. Additionally, the interconnection between the runner and each ligh...

A fabrication method for hollow integration rod suitable for high temperature operation, comprising the steps: (a) pre-fixing a set of mirrors to be a hollow integration rod by a light curable adhesive (such as UV curable adhesive); and (b) fixing those mirrors permanently by an inorganic adhesive. Wherein the mirrors can be a High Reflective Mirror with dielectric thin films, or it could be a High Reflective Mirror made of metallic thin film and coating a dielectric thin films by deposition for...

An image projector and a light tunnel are provided. The light tunnel includes: a light guide path in a form of a hollow tube having inner surfaces to reflect and guide light; a light entrance to allow light to enter the light guide path and a light exit to emit the light guided by the light guide path. The inner surfaces of the light guide path include inclined surfaces which are inclined in a manner that the aperture of the light guide path increases towards the light entrance. These inclined s...

Equipment for editing electrically coded page printing information which accepts an input from a keyboard (or tape reader) and stores coded information in an ultrasonic delay line. While the information is circulating, it is displayed on a Cathode Ray Tube by character generating circuits. The basic information is inserted in front of the displayed information and the whole is transferred to a secondary line ready to be fed out to a tape punch or type-setting machine. The spacing or justifying i...

A light guide light extraction mechanism can be formed in a predetermined maximum length to yield a predetermined light emission characteristic. Any shorter length segment removed from a predetermined end of the extraction mechanism and installed in a light guide of that shorter length causes the shorter length light guide to exhibit substantially uniform surface brightness. This obviates the need for cumbersome trial and error development of a different light extraction mechanism for each such ...

Illumination devices and methods of forming illumination devices, utilizing optical light films are disclosed. Joints useful in forming light carriers from optical light films are also disclosed.

A vision system is provided which allows viewing and/or inspection of an end surface of an optical fiber through a bulkhead on a backplane of a rack. By placing such a vision system on a mount configured to be inserted in the rack, the use of such a vision system does not require the rack design be modified or that other modules be removed. Preferably an adapter for mating the vision system with the bulkhead may be moved to position the adapter relative to the bulkhead housing the fiber of inter...
