Patent number: 9823544Abstract: Systems and methods for controlling stray light reflections are provided. An optical system includes an aperture having an optical axis passing therethrough, one or more optical elements disposed along an optical path, and a detector disposed along the optical path. The system further includes an optical housing disposed between the aperture and the detector. The interior surface of the optical housing includes a predetermined surface feature adapted to control reflections of stray light along the optical path between the aperture and the detector. A method of fabricating an optical housing includes forming a pattern comprising a predetermined surface feature on an interior surface of the optical housing. The predetermined surface feature is configured to control reflections of stray light along an optical path between an aperture at a proximal end of the optical housing and a detector at a distal end of the optical housing.Type: GrantFiled: March 12, 2014Date of Patent: November 21, 2017Assignee: DRS Network & Imaging Systems, LLCInventors: Kevin J. McIntyre, Brian R. Pekarek, Mark E. Durham, Ken Pietrasik

Patent number: 9658423Abstract: Embodiments of the invention are directed to a springless athermal lens assembly. In one embodiment, a spacer of a springless athermal lens assembly may compensate for defocus of the camera system due to thermal expansion of the lens assembly through the coupling of a spacer to an inner barrel and an outer barrel. The inner barrel comprises a lens cell assembly and a body. The outer barrel comprises a body. The spacer comprises a body having an inner surface and an outer surface. The outer surface of the spacer body is configured to be physically coupled to outer barrel body and the inner surface of the spacer body is configured to be physically coupled to the inner barrel body. A retainer ring is configured to engage with the outer surface of the spacer body and provide a radial force against the outer surface of the spacer body to securably engage the inner surface of the spacer body with the inner barrel body.Type: GrantFiled: September 29, 2015Date of Patent: May 23, 2017Assignee: DRS Network & Imaging Systems, LLCInventors: Eric J. Gustafson, Jeff R. Emmett, Rachel L. Cooper, Samuel E. Ivey, Rohan G. Rodney, Brian R. Pekarek, Patrick J. Cronkite, Mark E. Durham

Patent number: 9176298Abstract: Embodiments of the invention are directed to a springless athermal lens assembly. In one embodiment, a spacer of a springless athermal lens assembly may compensate for defocus of the camera system due to thermal expansion of the lens assembly through micro wedge mechanisms coupling the spacer to an inner and outer barrel. The inner barrel comprises a lens cell assembly and a body having a micro wedge slot. The outer barrel comprises a body having a micro wedge slot. The spacer comprises an inner barrel micro wedge and an outer barrel micro wedge. The spacer is configured to be physically coupled to the inner barrel through engagement of the inner barrel micro wedge and the inner barrel micro wedge slot. Further, the spacer is configured to be physically coupled to the outer barrel through the engagement of the outer barrel micro wedge and the outer barrel micro wedge slot.Type: GrantFiled: October 9, 2013Date of Patent: November 3, 2015Assignee: DRS Network & Imaging Systems, LLCInventors: Eric J.
