摘要： 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.

摘要： A technique is provided that uses a dual mode seeker (IR and LADAR) for precise target dynamics measurement, which extends stripping to a much higher altitude than ground based radar. Initial results show that this approach works to altitudes in excess of 100 km. Stripping becomes a reliable way to discriminate lighter weight decoys from reentry vehicles at altitudes and ranges consistent with planned divert capabilities for terminal phase missile defense. It is a finding of this invention that the LADAR will improve the spatial resolution by a factor of five over typical missile defense IR seekers using a common aperture. The LADAR provides a 3D angle, angle, range (AAR) image for each laser pulse which is used to extract the precise target state vectors.

摘要： A dual mode seeker for intercepting a reentry vehicle or other target is disclosed. In one embodiment, the seeker is configured with an onboard 3D ladar system coordinated with an onboard IR detection system, where both systems utilize a common aperture. The IR and ladar systems cooperate with a ground based reentry vehicle detection/tracking system for defining a primary target area coordinate and focusing the IR FOV thereon. The IR system obtains IR image data in the IR FOV. The ladar system initially transmits with a smaller laser FOV to illuminate possible targets, rapidly interrogating the IR FOV. The ladar system obtains data on each possible target to perform primary discrimination assessments. Data fusion is employed to resolve the possible targets as between decoys/clutter and a reentry vehicle. The laser FOV is expandable to the IR FOV. Robust and reliable discrimination is obtained at high altitudes.

摘要： 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.

摘要： 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.
