Filed:

Aug 10, 2000

Appl. No.:

09/636100

Inventors:

Mary Dominique O'Neill - Santa Barbara CA, US
William Hale Wellman - Santa Barbara CA, US

Assignee:

Raytheon Company - Waltham MA

International Classification:

G02B006/06

US Classification:

2502272, 250554

Abstract:

A sensor system for viewing the light energy of a scene has an imaging detector which converts incident light energy into an electrical signal. Two colors are separately imaged by the detector in two imaging regions. The imaging system for each color includes a color filter positioned between the scene and the respective region of the detector, an optical train that focuses filtered color scene energy, and an optical fiber bundle having an input end that receives the respective color scene energy from the optical train and an output end that directs the color scene energy onto the respective region of the detector using a nonlinear mapping. The optical fiber bundle is formed of a plurality of optical fibers wherein each of the optical fibers has an input shape and size at its input end and an output shape and size at its output end. The output shape and size are different from the input shape and size. The sensor system further includes an electronic device operable to read the electrical signal of the detector, and image-processing electronics.

Appl. No.:

10/790894

Inventors:

Mary Morabito O'Neill - Santa Barbara CA, US
Gregory K. Pierce - Santa Barbara CA, US
William H. Wellman - Santa Barbara CA, US

Assignee:

Raytheon Company - Waltham MA

International Classification:

H01L 27/00

US Classification:

2502081, 2502036

Abstract:

A position of a feature in a scene is located by forming an image of the feature using a segmented array having a plurality of array subelements. Each of the array subelements has an output signal. The output signals from at least two spatially adjacent array subelements are cooperatively analyzed to establish a data set reflective of an extent to which output signals responsive to the image of the feature are produced from exactly one or from more than one of the adjacent array subelements. The data set is used to reach a conclusion as to a location of the image of the feature on the segmented array. Increased positional accuracy is attained with no loss of sensitivity.

Appl. No.:

10/615133

Inventors:

Mary Morabito O'Neill - Santa Barbara CA, US
William H. Wellman - Santa Barbara CA, US

Assignee:

Raytheon Company - Waltham MA

International Classification:

B64D 1/18

US Classification:

89 111

Abstract:

An object such as an aircraft in flight is obscured from infrared detection when viewed from an external viewing location. The method includes providing the object having an externally viewable hot region associated therewith, wherein the hot region has a temperature greater than 150 C. A source of an obscuring agent is provided, wherein the obscuring agent comprises a mixture of carbon dioxide gas and water vapor. The obscuring agent is ejected from a dispensing location so as to flow between the hot region and the external viewing location. The obscuring agent has a temperature of less than that of the hot region.

Assignee:

Raytheon Company - Waltham MA

International Classification:

H01L 27/00

US Classification:

2502081, 348315, 348340

Abstract:

An imaging sensor system includes an optics system that images a point feature of a scene at an image plane with a blur-circle image having a blur diameter, and a detector array at the image plane. Special array patterns and signal detector logic are used to improve the accuracy of the determination of the object location. In one form, the detector array is a one-dimensional detector array comprising a plurality of detector subelements each having a width of from about to about 5 blur diameters, and a length of n blur diameters. Each detector subelement overlaps each of two adjacent detector subelements along their lengths. An overlap of each of the two adjacent detector subelements is m blur diameters, and a center-to-center spacing of each of the two adjacent detector subelements is nblur diameters. The value of n is equal to about 3m, and the value of m is equal to about n/2. In another form, the detector is a two-dimensional detector array of detector subelements.

Inventors:

Mary O'Neill - Santa Barbara CA, US

International Classification:

B64D001/04
F41F005/00

US Classification:

089/001110

Abstract:

A method for protecting an aircraft against a threat that utilizes an infrared sensor includes providing a plurality of dispensable infrared sources transported in an infrared-source dispenser with the aircraft. A set of infrared-emitting properties of the infrared sources is selected responsive to a set of infrared detecting characteristics of the infrared sensor. A modulated pattern of the infrared sources is dispensed from the infrared-source dispenser responsive to at least one of the set of infrared detecting characteristics of the infrared sensor, and a geometric engagement scenario of the aircraft and the threat.

International Classification:

G02B 21/36
H04N 5/232

Abstract:

An autofocus system includes an imaging device, a lens system and a focus control actuator that is configured to change a focus position of the imaging device in relation to a stage. The electronic control unit is configured to control the focus control actuator to a plurality of predetermined focus positions, and activate the imaging device to obtain an image at predetermined positions and then apply a spatial filter to the obtained images. This generates a filtered image for the obtained images. The control unit determines a focus score for the filtered images such that the focus score corresponds to a degree of focus in the obtained images. The control unit identifies a best focus position by comparing the focus score of the filtered images, and controls the focus control actuator to the best focus position corresponding to the highest focus score.
