Publication number: 20080144156Abstract: The camera or periscope system may include a taking lens, a beam steering device, a relay device, and an image rotation device. The camera or periscope system can be used to image in situations where the camera is not easily redirected to view a desired object of interest. The camera or periscope system is designed to be fixed to a mounting platform where the taking lens can be configured to point to the desired object of interest.Type: ApplicationFiled: December 12, 2007Publication date: June 19, 2008Applicant: SNAKEHEAD TECHNOLOGIES, LLCInventors: Ronald C.

Patent number: 7347561Abstract: A color management system for use with projection displays includes, for example, two or more analyzers positioned to receive light beams as they are emitted from the panels of a color management system. The analyzers are positioned to receive the light beams directly from the image assimilators before the light has passed through another optical element such as a light combiner. The analyzers are configured for producing filtered light outputs with improved contrast relative to the incoming light beams. By positioning the analyzers to receive the light beams directly from the image assimilators, i.e., prior to passage through other optical elements, the analyzers are able to remove substantially all of the noise before it has become indistinguishable, on the basis of polarization, from the light that comprises the desirable image. Accordingly, this embodiment produces images having dramatically improved levels of contrast relative to prior art systems.Type: GrantFiled: February 7, 2005Date of Patent: March 25, 2008Assignee: JDS Uniphase CorporationInventors: Clark Pentico, Michael Newell

Patent number: 7252399Abstract: The present invention relates to a folded front end unit used in a light engine of a projection display device. The front end unit comprises a light source for generating a beam of light, and a lightpipe for providing spatial uniformity to the beam of light. Polarization-dependent front end units include polarization beam splitters for separating the light into orthogonally polarized sub-beams, and a polarization rotating element, e.g. a waveplate, for rotating the polarization of one of the sub-beams. In accordance with the present invention, a prism is positioned between the light source and the lightpipe for reflecting the light into the lightpipe. The difference in refractive index between the air and the prism decreases the cone angle of the beam of light enough to effectively increase the distance between the light source and the lightpipe to compensate for the added distance required to fold the light.Type: GrantFiled: August 12, 2004Date of Patent: August 7, 2007Assignee: JDS Uniphase CorporationInventors: John Ferri, Michael Newell, Clark Pentico

Patent number: 7212347Abstract: This invention discloses a reflective illumination system for supplying an optical radiation beam along a folded path for illuminating a planar object. The system includes a radiation source, and two facing parabolic dish-shaped arrays of parabolic or dished reflectors. Divergent light received from the light source incident on a first of the arrays is reflected as a larger collimated beam comprising plural separated sub-beams. Each of the reflectors or facets from the first array directs one of the sub-beams to a facet on the second array. The second array reflects the light it receives with a substantially uniform intensity onto a rectangular target location.Type: GrantFiled: December 7, 2004Date of Patent: May 1, 2007Assignee: JDS Uniphase CorporationInventors: Clark Pentico, Unsig Min, Weimin Shi

Patent number: 7108374Abstract: A color management system for use with projection displays includes an image assimilator and an analyzer. The image assimilator comprises a panel that produces a light beam comprising spatial information. The image assimilator also comprises a field lens positioned to receive the light beam and configured to emit a converging light beam whose cross-sectional area decreases with distance from the field lens. In an exemplary embodiment, a plurality of image assimilators and associated analyzers are included, each having a field lens for emitting a converging light beam. The analyzers are configured for producing filtered light outputs with improved contrast relative to the converging light beams. In addition, the converging nature of the field lens emitted light beams enables the size of the analyzers and other downstream components to be minimized. Accordingly, this embodiment produces images having dramatically improved levels of contrast with reduced size relative to prior art systems.Type: GrantFiled: January 11, 2005Date of Patent: September 19, 2006Assignee: JDS Uniphase CorporationInventors: Clark Pentico, Michael Newell

Patent number: 7104650Abstract: A color management system for use with projection displays includes, for example, two or more analyzers positioned to receive light beams emitted from corresponding image assimilators, which each comprise a transmissive panel and a polarizing beamsplitter. Each analyzer is positioned to receive a light beam directly from an associated image assimilator before the light has passed through another optical element such as a light combiner. The analyzers are configured for producing filtered light outputs with improved contrast relative to the incoming light beams. These closely-coupled analyzers are able to remove substantially all of the noise before it has become indistinguishable, on the basis of polarization, from the light that comprises the desirable image. In an exemplary embodiment, an optical isolator is positioned to receive both a light output from a color management system and a reflection of the light output. The optical isolator is configured for isolating the light output from the reflection.Type: GrantFiled: February 7, 2005Date of Patent: September 12, 2006Assignee: JDS Uniphase CorporationInventors: Clark Pentico, Michael Newell

Patent number: 7018058Abstract: A reflector, light source, phase retarder, and linear polarizer configured to increase a single-polarization output beam by converting wrong-polarization light into correct-polarization light. The linear polarizer reflects the wrong-polarization light and transmits the correct-polarization light. The phase retarder converts the wrong-polarization light into correct-polarization light, which is then transmitted by the linear polarizer.Type: GrantFiled: July 22, 2005Date of Patent: March 28, 2006Assignee: Intel CorporationInventors: Michael O'Connor, Clark A.

Patent number: 6971747Abstract: A color management system for use with projection displays includes, for example, a separating polarizing beamsplitter, a compensating prism group, an image assimilator, and a combining polarizing beam splitter. In accordance with an exemplary embodiment, the separating polarizing beamsplitter receives a bi-oriented light input and separates it into two output beams, one comprising a first component and the other comprising a second component. The image assimilator receives an output light beam from the separating polarizing beamsplitter, transmits the light output to one or more corresponding microdisplays, receives one or more modified outputs from the microdisplays, and emits an output comprising those modified outputs to a combining polarizing beamsplitter.Type: GrantFiled: December 23, 2004Date of Patent: December 6, 2005Assignee: JDS Uniphase CorporationInventors: Michael P.
