US Patent:

59531550, Sep 14, 1999

Filed:

Feb 19, 1997

Appl. No.:

8/801692

Inventors:

Robert A. Eckel - Andover MA
Michael E. Couture - Litchfield NH

Assignee:

Raytheon Company - Lexington MA

International Classification:

G03B 1306
G02B 1700
G02B 2300

US Classification:

359432

Abstract:

An optical system having a selected one of a pair of fields of view. The optical system includes a primary reflector; a secondary reflector; a refractive optical system; and a drive. The drive orients the secondary reflector to a first region in optical alignment with the primary reflector to provide the optical system with one of the pair of fields of view and for reorienting the secondary reflector to a second region out of optical alignment with the primary reflector and orienting the refractive optical system at the first region to provide a refractive optical system with a second one of the pair of fields of view. The optical system includes a detector and a second refractive optical system disposed between the first region and the detector. The detector comprises an array of detector elements. A processor is provided for processing energy from pixels formed by plurality of detector elements having a smaller area when the energy is directed through the secondary reflector than when the energy is directed through the first-mentioned refractive optical system.

Assignee:

Raytheon Company - Lexington MA

International Classification:

H01J 4014

US Classification:

250208

Abstract:

An imaging optical system is described including an array of photodetectors, each photodetector having a surface, and a focusing system for focusing a beam of electromagnetic infrared energy on the surface of at least one of the photodetectors. The focusing system further includes a technique for periodically defocusing the beam of electromagnetic infrared energy on the surface of at least one of the photodetectors. With such an arrangement, a scanning and focusing system is provided wherein fixed pattern noise can be decreased.

Daniel Y. Ang - Quincy MA

Assignee:

Raytheon Company - Lexington MA

International Classification:

H01L 27146

US Classification:

2503384

Abstract:

An infrared detector array having a plurality of infrared detectors arranged in a matrix of rows and columns in a first semiconductor body; and, a plurality of integration/read circuits arranged in a matrix of rows and columns in a second semiconductor body, each one of the plurality of integration/read circuits being in vertical registration with, and electrically connected to, a corresponding one of the plurality of detectors. Each one of the integration/read circuits includes: a capacitor; a first transistor, electrically coupling the capacitor and the corresponding one of the detectors during an integration mode, for enabling current generated in the detector in response to impinging radiation to pass from the detector to the capacitor for integration; and a second transistor, electrically coupling the charge built-up on the capacitor during the integration mode to an output bus during a subsequent read mode. A reset circuit, laterally displaced from the integration/read circuitry, is coupled to the output bus, for discharging the charge built-up on the capacitor during the integration mode and for discharging charge generated in the detector during a subsequent reset mode.

Assignee:

Raytheon Company - Lexington MA

International Classification:

G02B 702

US Classification:

359823

Abstract:

An infrared energy detection system having an infrared detector and a cooling system including a fluid coolant for cooling the infrared detector. An optical system is provided for directing infrared energy from a target to the detector though an optical system. The optical system includes a housing having a plurality of stops, each one of the stops corresponding to one of a plurality of fields of view of the optical system. A first lens is fixed within the housing. A second lens is slidably mounted within the housing and engageable by the plurality of stops. The second lens has a first resting position when engaging a first one of the stops. A fluid actuator system is provided for sliding the second lens away from the first stop to a second resting position when engaging the second stop.
