Abstract: An apparatus includes a first substrate of a first material having a first bonding surface, and one or more fluidic channels open at a plane of the first bonding surface. The apparatus also includes a different second material disposed on the first substrate. The second material connects two different portions of the one or more fluidic channels. An outer surface of the second material is at the plane of the first bonding surface at positions between the two portions. The apparatus also includes a second substrate having a second bonding surface in contact with the first bonding surface, the second substrate configured to confine fluid flow within the one or more fluidic channels. In a Joule-Thompson cryocooler apparatus, the first material is a first thermally insulating material and the second material is a thermally conductive material and the second substrate is made of a second thermally insulating material.

Abstract: A method includes etching one or more fluidic channels into a first substrate made of a first material according to a first spatial pattern. The method also includes, after etching the fluidic channels, then separately etching a space in the first substrate according to a different second pattern that includes at least one connection between at least two different portions of the fluidic channels. The method still further includes depositing a different second material into the space. The method yet further includes bonding a different second substrate to the first substrate to enclose the fluidic channels to configure them to contain or pass one or more fluids. For fabricating a Joule-Thomson cooler, the first substrate is made of a first thermally insulating material; the second material is a thermally conducting material; and the second substrate is made of a second thermally insulating material.

Abstract: Systems and methods of acquiring large field of view, high-resolution image data are discussed herein. Techniques and devices relate operation and composition of systems for acquiring large field of view, high-resolution image data. Such systems may include a first sensor chip assembly (SCA) in an interlaced focal plane array (FPA), the first SCA having a length, a width, and a resolution; a second SCA in the FPA, the second SCA having the same length, width, and resolution; and a field of view (FOV) adjustment device that moves the FOV of the FPA so that it can observe different scenes. In some such systems, the first and second SCAs are arranged relative to each-other in a first spaced array extending along a first dimension of the FPA such that there is an intentional gap between the first and second FPAs along the first dimension.

Abstract: 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.

Abstract: A multi-mode detector and detection method that utilize shared optical components to detect multiple different incoming wavelengths of energy. Partial de-focusing of incoming light enables imaging and non-imaging outputs from the same detector. Analog and digital pixels enable mixed-mode output. Selective filtering at the detector enables the simultaneous detection of two or more wavelengths of light. Signal processing hardware and algorithms enable the system to simultaneously provide integrated and multi-channel analog outputs to guidance and display systems.
