Patent number: 5625738Abstract: The present invention relates to an optical system for providing uniform illumination of a light valve. The light source is an extended source generally emitting a non-uniform spatial distribution of light power. Source light is focused into the entrance end of a light transmitting tunnel having reflecting interior wall surfaces and having cross sectional and length dimensions chosen to deliver, at the exit end of the tunnel, light which is substantially uniform in power distribution over the surface area of the exit end. This is caused by multiple reflections from the tunnel walls. The exiting light is advantageously used to illuminate uniformly a light valve. The tunnel may be tapered to alter the exit angular aperture. The tunnel may be hollow or filled with a transparent material. In addition, the tunnel may be segmented and folded to provide a joint which conforms tunnel geometry to given spatial limitations between source and valve.Type: GrantFiled: June 28, 1994Date of Patent: April 29, 1997Assignee: Corning IncorporatedInventor: Simon Magarill

Patent number: 5619370Abstract: An optical apparatus that enables an object at a first location to be viewed from a second remote location. The optical apparatus includes at least one objective lens assembly that views the object at the first location. The objective lens assembly focuses the viewed image onto the input plane of an image conduit. The fiber optic conduit propagates the image to the second remote location, wherein the image is projected from the image conduit onto the back surface of a substantially transparent planar member. The back surface of the planar member is not highly polished. As a result, the image projected onto the back surface does not pass directly through the planar member. The reflections caused by the unpolished nature of the surface allow the image to be viewed on the back surface of the planar member through the body of the planar member.Type: GrantFiled: March 28, 1994Date of Patent: April 8, 1997Inventor: Patrick J. Guinosso

Patent number: 5594593Abstract: An optical rear view system for a vehicle, having a reflector mounted to receive light from objects to the rear of the vehicle and to reflect it towards an observer, is provided with at least one further optical component between the reflector and the observer effective to direct towards the observer, by refraction or reflection, a portion of the light which upon reflection at the reflector is not directed towards the observer, whereby to provide a wider field of view than that obtainable from the reflector alone. The reflector is positioned forwardly of the observer so as to be in his field of view and the surface of the system on which light from an object behind the vehicle is first incident lies at an acute angle to the longitudinal axis of the vehicle and is inclined such that a forward part of the incident surface is further from the vehicle axis than a rearward part.Type: GrantFiled: September 16, 1993Date of Patent: January 14, 1997Inventor: Peter J.

Patent number: 5519543Abstract: An optic system is provided for a down hole camera. The system includes an elongated tubular housing constructed from thermal insulating material. A front lens group and rear lens group are mounted within the housing adjacent opposite ends. The front and rear lens groups are thermally isolated from one another through the provision of two spaced windows therebetween that extend across and seal a light pathway running through the tubular housing. Preferably, the windows are sealingly mounted within the housing so as to define a vacuum chamber therebetween within the wall of the housing.Type: GrantFiled: October 4, 1993Date of Patent: May 21, 1996Assignee: Hitwell Video, Inc.Inventors: Mark S. Olsson, Michael S. DiMascio

Patent number: 5506424Abstract: A mounting device for a laser light source comprising fixed and mobile platforms which are generally cylindrical in shape, the fixed platform being slideably receivable within an optical tube. Each of the platforms has both one closed and one open end, the closed end defining a centrally-located socket for receiving a spherical bearing and at least three holes spaced equidistant from each other. The holes in the fixed platform are alignable with those in the mobile platform. In assembled relation, the spherical bearing is juxtaposed between the two platforms and held in place by three clamping screws. The shank of each of these clamping screws extends through one of the holes in the fixed platform, past the spherical bearing, and threadedly engages a hole in the mobile platform. Adjustment of the boresight, or alignment with a target, of the laser beam is accomplished by tilting the mobile platform so that its longitudinal axis is disposed at a slight angle to the longitudinal axis of the fixed platform.Type: GrantFiled: January 6, 1995Date of Patent: April 9, 1996Inventor: Steve Wilcken

Patent number: 5473408Abstract: A system is described for recycling radiation reflected by an illuminated patterning mask in a via-hole drilling or exposure tool. The mask is illuminated by high-energy laser radiation, and the illuminated region is imaged onto a substrate by a projection, proximity, or contact method. The source radiation is suitably shaped by a lens assembly and focused into an optical intensity homogenizer with the desired numerical aperture. The homogenizer has the base function of converting the focused beam to self-luminous light required for drilling of via-holes or other processes accomplished by the tool, while maintaining the numerical aperture of the beam. The homogenizer also participates in the radiation-recycling function. An apertured reflector allows radiation from the source to enter the homogenizer. The radiation passing through and exiting the homogenizer is image by a lens to illuminate a portion of the mask.Type: GrantFiled: July 1, 1994Date of Patent: December 5, 1995Assignee: Anvik CorporationInventors: Jeffrey M. Hoffman, Kanti Jain

Patent number: 5430575Abstract: An optical rotation device with infinite depth of field for transmitting optical images along an optical axis and selectively rotating the image about the optical axis, while preserving all of the three dimensional characteristics of the image. The optical rotation device consists of two optical elements optically coupled in series, each of which produces an inversion of the image about an axis orthogonal to the optical axis. Rotation of the image by any angle in the plane normal to the optical axis is achieved by rotating the two optical elements relative to one another about the optical axis.Type: GrantFiled: April 25, 1994Date of Patent: July 4, 1995Assignee: Quantum Optical Devices, Ltd.Inventors: George Sudarshan, Randall G.

Patent number: 5412510Abstract: An imaging optical system for compensating for changes of temperature according to the present invention corrects a focal point for an entire optical system due to temperature change by changing a relative distance between a lens and a light receiving element. To this end, a correcting member, which expands and contracts due to temperature change, is disposed between the lens and the light receiving element. Moreover, the coefficient of thermal expansion is set to such a value so as to be able to substantially correct for the focal point change. According to another aspect of the present invention, the optical system includes a lens system which has at least a positive lens and a negative lens in order to offset the effect of the temperature change.Type: GrantFiled: November 12, 1992Date of Patent: May 2, 1995Assignee: Asahi Kogaku Kogyo Kabushiki KaishaInventors: Takashi Iizuka, Yasunori Arai, Yoshihiro Yamazaki
