Patent number: 10429565Abstract: In one aspect, the present invention provides an optic, which comprises a light pipe extending from a proximal end to a distal end about an optical axis, said light pipe being adapted to receive at its proximal end at least a portion of light emitted by a light source. The optic further comprises a central reflector optically coupled to said distal end of the light pipe for receiving at least a portion of the light transmitted through the light pipe and reflecting said received light, a peripheral reflector optically coupled to said central reflector for receiving at least a portion of said reflected light, and an output surface. The peripheral reflect is configured to redirect at least a portion of the light received from the central reflector to said output surface for exiting the optic.Type: GrantFiled: July 28, 2017Date of Patent: October 1, 2019Assignee: Fraen CorporationInventors: James Preston, Brien J. Housand, Michael Zollers

Patent number: 9255688Abstract: In some aspects, an optic is disclosed that includes a light input interface having a rippled surface that can mix the light incident thereon as the light propagates within the optic from the rippled surface to a peripheral surface of the optic, which is configured to redirect the light incident thereon to an output surface through which the light exits the optic.Type: GrantFiled: March 6, 2013Date of Patent: February 9, 2016Assignee: Fraen CorporationInventors: Michael Zollers, James Preston, Brien J.

Patent number: 9146016Abstract: Optics and optical devices and systems are disclosed that employ a plurality of refractive and/or reflective optical elements, such as lenses and mirrors, with different shapes to achieve a desired illumination pattern. In various aspects, a plurality of lenses in which at least two of the lenses have different boundary shapes are arranged, e.g., according to a predefined pattern, to receive light from one or more light sources and to redirect the received light to form collectively a desired far-field illumination pattern. For example, the lenses can be configured such that the far-field illumination pattern has a boundary shape that is different from the boundary shape of a far-field illumination pattern that can be provided individually by the lenses.Type: GrantFiled: March 29, 2013Date of Patent: September 29, 2015Assignee: Fraen CorporationInventors: Michael Zollers, James Preston, Brien J.

Patent number: 6359681Abstract: In a FLIR/laser based targeting and imaging system, the ability to recognize, detect, locate, and/or track targets in an area of interest is significantly improved by reducing the fixed and dynamic alignment errors between the IR LOS and the laser LOS. Fixed alignment errors are reduced with an improved internal boresight module and corresponding boresight method. Dynamic alignment errors are reduced with an opto-electric subsystem that employs a single pitch bearing and a common pitch/yaw afocal for both the laser energy and the IR energy. A segmented window in the system housing includes a circular EMI grid pattern which significantly reduces the amount of off-axis EMI entering the optical pathways, and improved signal processing techniques are employed to enhance the quality of the IR image after the image has been digitized.Type: GrantFiled: August 9, 2000Date of Patent: March 19, 2002Assignee: Lockheed Martin CorporationInventors: Brien J.
