Abstract:
An optical fiber manifold is provided for coupling light from an illumination source to a plurality of spaced, large diameter output fibers, or "light pipes", which are used for a variety of purposes, such as illuminating pools, spas, hazardous material zones, jail cells, and other applications where direct lighting is dangerous, difficult to maintain, or subject to vandalism. The manifold comprises a light converging element, which may be either a lens or a reflector, for converging light separately on each of the spaced optical fibers. The light converging element is segmented, with each segment corresponding to one of the optical fibers, and is precise enough that substantially all of the convergent light is received by the respective cores of each of the spaced output fibers, thereby minimizing light loss.

Abstract:
The inventive system, which is used in transmitting illumination from a central source to a variety of remote locations, efficiently couples the light originating from an arc lamp, or similar source, into a multiplicity of flexible macroscopic fibers. The combination of the several elements of the inventive system results in a very efficient transfer of the energy of the light source to the fibers. The system also provides a very flexible mechanical means for distributing the energy to the fibers and to the remote locations at which the light is used.
Lcd Projection System Which Aligns The Larger Beam Spread Angle Of The Light Source With The Larger Acceptance Angle Of The Light Valve And A Nonimaging Reflector For An Illumination System

International Classification:

US Classification:
359 40
Abstract:
A projection system comprising a liquid crystal light valve having a wider acceptance angle for incident light in a first direction than in a second direction transverse to the first direction and an illumination system. The illumination system provides light to the liquid crystal light valve at a greater beam spread angle in the first direction than in the second direction. The system also includes projection optics for receiving light from the liquid crystal light valve and projecting such light toward a projection surface.

Portable Collapsible Display And Projection Apparatus

Assignee:
Prolux Corporation - San Juan Capistrano CA
International Classification:
G03B 2130
US Classification:
353119
Abstract:
A portable collapsible liquid crystal display apparatus which includes a base, and a relatively large viewing screen having a width corresponding substantially to the overall width of said base and which, together with a first planar member of the same size, are pivotally mounted on the base. When the apparatus is in its viewing mode, the screen is turned to an upright position on the base with the mirror in an inclined position extending downwardly behind the screen to reflect images over the entire rear surface of the screen. When the unit is in a collapsed mode, the screen is folded down over the base and the mirror is folded down on top of the screen with its reflective surface facing the screen and with its rear surface forming a protective cover for the screen. The linkage mechanism which couples the screen and mirror to the base includes relatively wide links which also serve to shield the rear surface of the screen from ambient light when the screen is in its upright viewing position. An appropriate optical system is mounted on the base, which includes a liquid crystal light valve, an appropriate light source, a fixed mirror, and a wide angle lens for projecting images from the light valve to the fixed mirror to be reflected through the first-named mirror to the rear surface of the screen.
Adjustment of the field-of-view angle in a surgical microtelescope from the outside of the patient's body is made possible by including in the objective optical system an assembly of mutually movable prisms. The prisms can be moved by a wire running alongside the optical fibers which convey illumination through the tube. In one embodiment, a movable prism pivots with respect to a fixed prism about an axis coincident with the axis of the image as it is transmitted between the prisms; in another embodiment, a partially silvered prism is slidable between two fixed prisms so as to pick up the image from one of them in one position, and the image from the other in the other position. Apparatus in the eyepiece is also disclosed to compensate for the rotation of the image when the pivoting embodiment is used.

International Classification:
G02B 642
US Classification:
385118
Abstract:
A visible helium neon beam is used as an aiming beam to establish a spot at which a carbon dioxide beam also focuses. The carbon dioxide beam is then employed to vaporize biotic material. A distal end of an articulated arm may couple with the micromanipulator to direct the carbon dioxide beam from the laser through a waveguide and into the micromanipulator. Another aspect of the invention includes introducing the aiming beam into the waveguide through a dichroic mirror positioned in a knuckle joint of the articulated arm. In one embodiment, a laser diode generates the visible light of the aiming beam, and is disposed proximate to the distal end of the articulated arm.
Endoscope With Multiple Section Image Transmitting Rod

International Classification:
A61B 106
US Classification:
128 6
Abstract:
An endoscope comprising a body, including an elongated tubular distal section adapted for insertion into a patient and optics for transmitting an image through the distal section so that the image can be viewed at a viewing location. The image-transmitting optics include an elongated image-transmitting rod for transmitting the image to at least a region of the distal section. The image-transmitting rod is subject to breakage by bending forces and is divided longitudinally into discrete elongated rod sections to thereby reduce the likelihood of breakage by bending forces.
