Patent number: 8329299Abstract: A method for depositing sol-gel derived coatings on substrates to form coated substrates includes the steps of providing a first solution including at least one sol precursor and at least one solvent. A water comprising solution is added to the first solution to form a sol-gel. The sol-gel is deposited on a substrate. The sol-gel layer on the substrate is dried/cured at a temperature ?100° C. for at least 10 minutes to form a solid layer, wherein the solid layer has a thickness from 50 nm to 110 nm. The depositing and curing steps are repeated at least once until combined thickness of the solid layers forms a coating of a predetermined thickness. The resulting solid layers are low water content layers that can be evidenced by transmission measurements. The coated substrate can be an IR transmissive substrate having a recrystallization temperature <130° C.Type: GrantFiled: March 31, 2008Date of Patent: December 11, 2012Assignees: University of Central Florida Research Foundation, Inc., Lockheed Martin Missiles and Fire ControlInventors: Sudipta Seal, Erik R. Brinley, Suresh Babu Krishna Moorthy, Abhilash Vincent, David Reid, Clara Rivero

Publication number: 20120230602Abstract: An apparatus and method for acquiring image data from a scanned, multi-bank time-delay and integrate (TDI) focal plane array (FPA) detector. Specifically a method and apparatus for warping and combining sequentially-acquired image data of a scene portion from multiple TDI detector banks into a single image having improved image quality, thereby providing improved FPA sensitivity. Also, a method and apparatus for enabling sensitivity and areal rate trade-offs in a multi-bank, scanning TDI FPA based on the number of TDI banks being used for sequential imaging of the same scene portion.Type: ApplicationFiled: August 22, 2008Publication date: September 13, 2012Applicant: Lockheed Martin Missiles and Fire ControlInventors: Mark A. Goodnough, Gene D. Tener

Patent number: 7572512Abstract: An infrared transmissive article includes an infrared transmissive substrate and a single layer anti-reflective (AR) composite broadband sol gel coating on a surface of the substrate. The AR coating includes a first chalcogenide including compound, and a second chalcogenide including compound intermixed with the first chalcogenide including compound. The percentages of the first chalcogenide and the second chalcogenide in the AR coating are selected to provide a refractive index of the AR coating that approximates the square root of a refractive index of the substrate.Type: GrantFiled: March 2, 2007Date of Patent: August 11, 2009Assignees: University of Central Florida Research Foundation, Lockheed Martin Missiles and Fire ControlInventors: Erik Brinley, Sudipta Seal, Edit Braunstein, Leslie Kramer

Publication number: 20080165359Abstract: This invention solves a problem of registration and improves signal-to-noise ratio (SNR) when using division-by-focal-plane array to produce multiple polarization images. This is achieved by processing a sequence of angular-position-dithered frames to generate a high-definition, Nyquist-sampled, integrated image for each of the polarizations. The integration method transforms individually under-sampled, high-resolution image frames into resultant high-resolution frames that meet the Nyquist sampling criterion. During the resampling transformation, each polarization or waveband is resampled to produce precise registration to the other polarizations, since registration offsets are fixed and defined by the arrangement of the polarized pixels in the focal-plane-array. In the most straight-forward implementation, these offsets would be integer pixel shifts in X and Y.Type: ApplicationFiled: January 9, 2008Publication date: July 10, 2008Applicant: Lockheed Martin Missiles and Fire Control - OrlandoInventors: Barry G.

Patent number: 7391925Abstract: A system and method for estimating noise using measurement based parametric fitting non-uniformity correction is disclosed. Fixed pattern noise (“FPN”) is estimating from an overall noise component within a detection system to enhance candidate target detection and tracking. A sensor in the detection system receives energy, such as radiant flux, that is converted to a digital image. A non-uniformity correction device generates an estimated FPN according to an applicable temperate range and integration time. A memory storing an array of coefficients is accessed to determine the estimated FPN. The valves within the array of coefficients are based on actual FPN measurements that are parametrically fitted.Type: GrantFiled: December 4, 2003Date of Patent: June 24, 2008Assignee: Lockheed Martin Missiles & Fire ControlInventors: Hai-Wen Chen, Felix M.
