Patent number: 8900890Abstract: Techniques are disclosed for improving the quantum efficiency of photocathode devices. The techniques allow for an increase in the optical thickness of the photocathode device, while simultaneously allowing for an increase in the probability of electron escape into the vacuum of the device. The techniques are particularly useful in detector and imaging. In one embodiment, a photocathode device is provided that has an array of corner cubes fabricated in a surface of the photocathode. The corner cube array is made of the same material as the photocathode layer. The device may be, for example, a detector or image intensifier that operates in the UV, visible, and IR light spectrums, and may further include a gain medium, anode, and readout device. Techniques for forming the device are also provided.Type: GrantFiled: October 4, 2013Date of Patent: December 2, 2014Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Michael E.

Patent number: 8371201Abstract: A method and apparatus is provided for increasing the effectiveness of destroying selected objects in a target cloud by prioritizing the objects detected in a large aperture IR detector aboard a carrier vehicle and sequentially illuminating the detected targets with coded laser radiation, followed by the launching of multiple miniature kill vehicles from the carrier vehicle, with each kill vehicle assigned to a differently-coded object in the target cloud due to the reflection back of the coded returns, thus to permit directing of individual miniature kill vehicles to a specific object in the target cloud prior to a handoff to an IR heat seeker in the miniature kill vehicle, actuated to guide the kill vehicle for a final kill.Type: GrantFiled: August 18, 2005Date of Patent: February 12, 2013Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Michael E.

Patent number: 8218012Abstract: A sensor is used to detect and track a plurality of objects by using a separate track window for each object. Such sensors may be electro optical or infrared. Each object of interest (potential target) in the sensor FOV has a unique track window assigned. This allows independent control of video frame summing for each object to maintain a constant (optimized) signal to noise ratio (SNR) over an extremely large signal dynamic range and reduces track jitter by the simultaneous tracking of multiple objects.Type: GrantFiled: March 18, 2008Date of Patent: July 10, 2012Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Michael E DeFlumere, William E Shaw, Walter P Watson

Patent number: 8168936Abstract: Techniques are disclosed that can be used to interface a sensor circuit with readout circuitry. The techniques can be employed, for instance, with microchannel plate (MCP) based devices used in numerous sensing/detection applications, and are particularly suitable for applications where it is desirable to interface an MCP having a relatively large active area to a readout circuit having a relatively smaller active area. The interface effectively decouples anode geometry from readout circuit geometry and also may be configured with flexible anode pad geometry, which allows for compensation of optical blur variations as well as a very high fill factor. The interface can be made using standard semiconductor materials and photolithography techniques and can be configured with thermal expansion qualities that closely track or otherwise match that of the readout circuitry.Type: GrantFiled: June 17, 2011Date of Patent: May 1, 2012Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Michael E.

Patent number: 8075144Abstract: A telescope design having an integrated baffle is disclosed herein. The integrated baffle is configured as both a baffle and a mirror support. The integrated baffle can be shaped to the F-cone between the primary and secondary mirrors of a given telescope design. The baffle design can be adjusted to minimize or otherwise reduce the total obscuration of the baffle to improve the optical throughput. The interior facing surfaces of the integrated baffle can be configured with corner reflectors, so that the detector views itself, instead of the baffle.Type: GrantFiled: November 20, 2008Date of Patent: December 13, 2011Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: William E.

Patent number: 7999216Abstract: Techniques are disclosed that can be used to increase the dynamic range of a microchannel plate (MCP) device, thereby eliminating the need for conventional techniques such as gating. In one example embodiment, an MCP device is provided that includes a plurality of channels, each channel for amplifying a photoelectron input to the channel and for producing an electron cloud at its output. The device further includes one or more charging switches associated with each channel for allowing charging current to flow so as to charge that channel in response to producing an electron cloud. In some such example cases, the plurality of channels and the one or more switches are implemented in silicon, and the one or more charging switches turn on only in the presence of the electron cloud produced at the corresponding channel output.Type: GrantFiled: March 9, 2009Date of Patent: August 16, 2011Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Michael E.

Patent number: 7926961Abstract: A telescope design is disclosed that has at least some of its interior facing surfaces configured with corner reflectors, so that a detector operatively coupled to the telescope views itself, instead of those surfaces. The corner reflectors may be on, for example, interior facing surfaces of a conventional baffle appended to the telescope and/or mirror supports or other structures inside the telescope housing that are within the detector's FOV. Likewise, the corner reflectors may be on interior facing surfaces of a baffle that is integrated into the telescope housing. In some such cases, the integrated baffle can be configured as both a baffle and a mirror support. The integrated baffle can be shaped to the F-cone between mirrors of a given telescope design, and/or configured to minimize or otherwise reduce the total obscuration of the baffle to improve the optical throughput.Type: GrantFiled: November 20, 2008Date of Patent: April 19, 2011Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: William E.
