Explosive Detection System Contract Award
December 2009 Information Systems Laboratories was recently awarded a contract by the Explosives Detection Subgroup of the Technical Support Working Group (TSWG). ISL will develop a detection and imaging system using mid-IR laser quantum cascade lasers (QCL). The system will be used to detect explosive absorption features and will be combined with visible/thermal imaging cameras. Advanced detection algorithms and image processing will be developed to determine the location and type of explosive, enabling efficient detection and threat resolution.
ISL Provides Support to the White House Commissioned Review of the U.S. Human Space Flight Plans Committee
October 2009 ISL was the main contractor providing safety and reliability analysis support for the various launch vehicle options considered by the Review of the U.S. Human Space Flight Plans Committee (a.k.a. the Augustine Panel). ISL personnel analyzed such options as Evolved Expendable Launch Vehicle (EELV) based crew launch options as well as Space Shuttle-based Heavy Lift options. The findings provided insights into the viability of final top-level options being proposed by the Augustine Panel’s final report.
ISL is Small Business Sponsor at 21st Annual NDIA Gold Coast Event
August 4, 2009 ISL participated as a Small Business Sponsor at the 21st Annual NDIA Gold Coast Event held in San Diego, CA. This year’s event was extremely successful with over 1500 attendees from government and industry, 229 exhibit booths, 31 poster displays, and 9 workshops. The event was co-sponsored by NAVFAC, SPAWAR, NAVSEA, NAVSUP and NAVAIR. As a small business sponsor and exhibitor, ISL staff had the opportunity to engage with the local Navy and industry community for this productive event which was held on the waterfront at the San Diego Convention Center. We look forward to Gold Coast 2010!
Development of a Double Pulse LIBS
July 22, 2009 Information Systems Laboratories has initiated an internal research and development effort to design and build a double pulse LIBS system. An order of magnitude or greater enhancement in the atomic emission signal peak is anticipated in comparison with a single pulse system for many different elements. The system will be based on a Nd:YAG laser system consisting of diode pumped master oscillator (MO), flashlamp pumped amplifier, beam expander and high resolution spectrometer. ISL is developing a double pulse MO system using two perfectly collinear pulses out of a single oscillator to ensure an overlap ablation spot at standoff distances of ~100m, to provide short pulse duration (~5ns) for good ablation, and to provide pump energy to the plasma via the second pulse. Full control of the first to second pulse ratio and interpulse separation will enable optimization LIBS signal. Diffraction limited beam quality is expected for high intensity on the target. This technology will be used as prototype to assist ISL in the development of remote chemical detection systems.
ISL Awarded NAVAIR Contracts
April 30, 2009 ISL’s Sensor Technology Operation (STO) was awarded two SBIR contracts by NAVAIR this year to develop E-field sensor technology for underwater sensing applications. ISL won Phase I awards for topic N091-019 (E-field and Acoustic Data Fusion) and topic N091-027 (Vertical E-field Sensing). Under these efforts, ISL will develop concepts and signal processing algorithms for a prototype ‘A-size’ buoy that collects both three axis E-field and acoustic sensor data. ISL plans to build and test prototype sensors as part of follow-on Phase II work. The additional sensor information provided by E-field sensors complements acoustic sensors and provides a way for false arm reduction and increased surveillance capability under adverse acoustic conditions in littoral waters.
Technical Support Working Group Contract Award
April 9, 2009 Information Systems Laboratories was recently awarded a Phase I contract by the Technical Support Working Group (TSWG) to develop a molecular detection and imaging system based on a mid-IR laser quantum cascade laser (QCL). The system will be used to detect explosive absorption features and will be combined with visible/thermal imaging cameras. Advanced detection algorithms and image processing will be developed to determine the location and type of explosive, enabling efficient detection and threat resolution.
