ASPECTAirborne Spectral Photometric Environmental Collection Technology
  • The primary mission of ASPECT is to provide information to the first responder in a form that is timely, useful, and compatible with existing infrastructures.
  • ASPECT can provide infrared & photographic images with geospatial chemical and radiologicalinformation.

Line Scanner RS-800MSIRLS

  • ASPECT Uses Three Primary Sensors:
    • An Infrared Line Scanner to image the plume
    • A High Speed Infrared Spectrometer to identify and quantify the composition of the plume
    • A Gamma-Ray Spectrometers for Radiological Detection

Advance Digital Spectrometers


top ten features
Top Ten Features
  • Digital Design – More stable, less drift, higher count rates, “cleaner” spectra i.e. better data.
  • No Internal or External Test Sources – No radioactive material transport issues. No lost or misplaced sources.
  • Self Diagnostic with Auto System Validation – An Advanced design enables a more self contained system requiring less operator interaction. Individual detector raw data is archived in the system

4. Multi-Peak U, K, Th Auto-Stabilization – Stabilizes in all areas, Faster, 3 min vs 30 min.

5. Individual Crystal ADC’s& Processing –

The high speed sampling of pulses allows for pulse analysis and DSP processing.

Resulting in improved pulse pile-up rejection, zero dead time & a higher throughput.

  • Wide Dynamic Range – From low level to 1,000,000+ cps for each crystal.
  • Individual Crystal Linearization with proper Poisson noise characteristics
top ten features2
Top Ten Features
  • Expandable

Unlimited number of crystals (limited only by weight considerations)

  • Wide range of Connectivity options – RS232 serial, TCPIP and USB. Utilizing data compression that allows for full spectral data transfer every second over wireless devices.
  • Modern Compact Design – Strong & Efficient Case, Modular, Meet FAA requirements
aspect gem project

Purpose: To improve the US EPA airborne gamma-screening and mapping capability of ground-based gamma contamination following a wide-area radiological dispersal device (RDD) or improvised nuclear detonation (IND) attack.

Goal: To develop the most advanced gamma-radiation detection capability mountable within an Aero Command 680 FL airframe.

EPA Homeland Security

ASPECT GEM project directly supports the EPA Office of Homeland Security focal area that directs the agency to: ”Develop appropriate/effective technologies to lessen the time frame for characterization and decontamination of contaminated widespread and populated areas following an RDD.”
