Abstract: A second imaging device such as a thermal imager adapted for use with a first imaging device such as an image intensifier night vision goggle system whereby the output image of the second imaging device is collimated and projected upon the objective lens of the first imaging device to provide an optically fused image to the viewer.

Abstract: On-board non-uniformity correction calibration methods for a microbolometer focal plane array in a thermal camera are disclosed. The methods include performing first calculations in the processor unit of the thermal camera to generate and apply a set of coarse correction bias voltages to the detector elements. The method also includes performing calculations in the external computer based on image data collected by the thermal camera with the coarse correction bias voltages applied to the detector elements to generate a set of fine correction bias voltages. The method also includes downloading the fine correction bias voltages to the thermal camera and applying the fine correction voltages to the detector elements to establish a fine calibration of the microbolometer focal plane array.

Abstract: An opposing first plate and second plate are slideably disposed with respect to each other using self-aligning plate registration means. Circuit board registration means and component registration means are provided for the initial X-Y alignment and registration of the circuit board and socket contact elements with one or more electrically conductive leads of an electronic component such as a focal plane array (FPA). A non-contact portion is provided on the first plate to eliminate plate contact with the first component surface which may comprise the lens of an FPA. The first and second plates are urged together such that an even, controlled and substantially planar compressive force is applied, permitting the efficient insertion of the electrically conductive leads into the socket contacts.

Abstract: A system and method are provided for removing a reticle from visualization in a displayed view in a binocular wherein the reticle is visible during direct scene view. The system includes a filter positioned between a display element and an eyepiece wherein a visual characteristic of the filter matches a corresponding characteristic of the reticle. These matching characteristics thereby render the reticle substantially “invisible” to the user. Exemplary filters can include a monochromatic filter and a polarizer.
