Patent number: 10331982Abstract: The Hy-ALERT processing system operates simultaneously on the data streams from visible and thermal imaging sensors and from hyperspectral imaging sensors. The visible and thermal image processing uses cognitive-inspired processing techniques that determine the salient content of the imagers based on the system user definition of salient content. The hyperspectral image processing uses anomaly detection and template matching techniques to determine the salient materials content of the observed scenes. Cross-correlation processing of the salient content of the various image and hyperspectral data streams enables the sensor systems to adapt their operating characteristics to optimize effectiveness in near real-time.Type: GrantFiled: March 13, 2017Date of Patent: June 25, 2019Assignee: Irvine Sensors Corp.Inventors: James W Justice, Medhat Azzazy, Virgilio Villacorta

Patent number: 10185033Abstract: The ACASS 3D LIDAR system operates in a fundamentally new manner combining features of flash LIDARS and scanning LIDARS simultaneously which enables mission and performance trades to be conducted by varying the sizes of illumination patches within the scenes being observed. Further the combination of these modes of operation into a single LIDAR system enables multiple modes of operation and multiple missions to be accomplished with single lasers obviating the need for multiple lasers and enabling significant simplification of beam control modes. Systems which result from the new, expanded size, weight, power, cost trade space enabled by the ACASS concept can provide new levels of performance at significantly reduced risks and costs The achievement of wide area, three dimensional imaging using a LIDAR sensor system is accomplished with one laser which operates using an eye safe fiber laser with very high puke 13 rates but very low energy per pulse.Type: GrantFiled: October 29, 2015Date of Patent: January 22, 2019Assignee: Irvine Sensors Corp.Inventors: James W Justice, Medhat Azzazy, Itzhak Sapir

Patent number: 10078137Abstract: A LIDAR system that can accommodate both a clear atmosphere and be adaptable to environments in which smoke, dust or other particulates (i.e., a degraded environment) exist in the atmosphere around the target is described. The system operates in two fields of regard: clear view mode (wide field of regard) and a degraded view mode (narrow field of regard). The wide field of regard allows the output laser energy to be concentrated over a large number of detector pixels and thus resulting in high scene scan rate. The narrow field of regard allows concentrating the laser output energy on fewer pixels to compensate for the loss of laser energy due to atmospheric degradation. The combination of the ROIC and LIDAR modes of operation result in a system that is capable of operation under clear and degraded environments.Type: GrantFiled: June 21, 2014Date of Patent: September 18, 2018Assignee: Irvine Sensors Corp.Inventors: David Ludwig, Alan C.

Publication number: 20160125606Abstract: There has been a significant advance in the capabilities of electro-optical sensors to search wide areas and provide data streams that contain information critical to system operators. The problem being addressed by this invention is the accurate and timely interpretation of the observations made by these sensor suites and the instantiation of the processing on practical low power, high throughput processors which enable deployment on a wide variety of platforms. The interpretation of sensor observations will also depend upon a) the general situation, e.g. level of hostility, and b) collateral data, e.g. normal or abnormal operations of the platforms themselves. Can accurate and timely situation awareness be achieved? Yes, humans do it all the time. Can it be done on small, ultra-low power, ultra-high throughput processors? Yes 3D stacked analog ASIC circuits enable such processors.Type: ApplicationFiled: October 29, 2015Publication date: May 5, 2016Inventors: James W.

Publication number: 20150268630Abstract: A high resolution holographic imaging system. A laser illuminator is configured to operate in two or more wavelengths sequentially and a phase modulator element configured to operate at three or more phase positions. The illumination beam is split into two parts and propagated into optically diffractive elements to define “top hat” signals from the received Gaussian signals.
