20140300502 | Millimeter Wave Energy Sensing Wand and Method - A millimeter wave energy sensing wand is disclosed. In a particular embodiment, the wand includes a housing adapted to be grasped by a hand of an operator, at least one pixel contained within the housing, where the at least one pixel adapted to detect millimeter or terahertz wave energy emissions, and an alarm, where the alarm is activated when an anomaly of the millimeter wave energy emissions is detected. In addition, the wand may include a digital signal processor for processing millimeter wave emissions detected by the at least one pixel to determine millimeter wave energy values and a memory device for storing the millimeter wave energy values. A comparison module or other similar means may be used for comparing the millimeter wave energy values detected by the at least one pixel to a background millimeter wave energy value that may be a moving average or an absolute value. | 10-09-2014 |
20120026336 | METHOD AND SYSTEM OF ENHANCED INTEGRATION OF MILLIMETER WAVE IMAGERY - A method and system of enhanced integration of millimeter wave imagery is disclosed. In a particular embodiment, the method includes performing a first scan of millimeter wave energy of a target and processing the first scan of millimeter wave energy to generate millimeter wave imagery of the target. The method also includes displaying a video image and the millimeter wave imagery of the target on a video monitor and determining whether the target is still or moving. In addition, the method includes processing a second scan of the millimeter wave energy of the target when the target is still and not moving and integrating the first scan and the second scan to increase a resolution of the millimeter wave imagery. | 02-02-2012 |
20110084868 | VARIABLE RANGE MILLIMETER WAVE METHOD AND SYSTEM - A variable range millimeter wave method and system is disclosed. In a particular embodiment, the system includes a primary mirror having an aperture to reflect millimeter wave energy to a secondary mirror, where the secondary mirror is disposed in front of the primary mirror and adapted to redirect the millimeter wave energy to a millimeter wave sensor/detector of a millimeter wave camera. The millimeter wave camera is configured to process the millimeter wave energy to visually detect concealed objects hidden on a target and an operating frequency of the millimeter wave camera is between 225 GHz and 275 GHz. In addition, the system includes a laser rangefinder, GPS and altimeter to determine a location of the target and to optimize a focus of the millimeter wave camera. A video monitor displays millimeter wave imagery and video images spatially and temporally relative to the millimeter wave imagery to aid targeting. | 04-14-2011 |
20090297039 | SOFTWARE METHODOLOGY FOR AUTONOMOUS CONCEALED OBJECT DETECTION AND THREAT ASSESSMENT - A system and method for autonomous concealed object detection and threat assessment. Image data is received from a millimeter wave imaging device comprising at least one scan of a scene. The image data is enhanced thereby creating enhanced image data comprising a plurality of enhanced image pixels. The enhanced image data is evaluated thereby identifying at least one subject within the enhanced image data. The subject is separated from a background within the enhanced image data. The contrast of the subject is enhanced within the enhanced image data. Concealed physical objects associated with the subject within the enhanced contrast image data are detected, thereby detecting at least one concealed object associated with the subject. A representation of the subject and the concealed physical object is displayed on a display device. | 12-03-2009 |
20090184861 | INCLUSION OF ASSESSMENT DATA IN MILLIMETER WAVE CONCEALED OBJECT DETECTION SYSTEMS - A millimeter wave object detection system includes a millimeter wave imager and a data entry device configured to assign assessment information to events where a concealed object is detected by an operator/observer or automated computer program interrogating imagery produced by the millimeter wave imager. A computer is programmed to store assessment data from the data entry device into a database, and statistical operations can be performed upon the database. | 07-23-2009 |
