FTIR

The FTIR utilized by ASPECT consist of a modified MR-254; high temporal resolution (75 Hz) system Dual input design with Signal port and Cold source reference port.
Two detectors are utilized including a 3 –5 and 8 – 12 micron providing coverage in the atmospheric IR window. Unit ready for operation in under 4 minutes after power-up. Chemical detection is automatic using a pattern recognition algorithm

A unique airborne emergency response tool, ASPECT is a Los Alamos/U.S. Environmental Protection Agency project that can put chemical and radiological mapping tools in the air over an accident scene. The name ASPECT is an acronym for Airborne Spectral Photometric Environmental Collection Technology.

Update, Sept. 19, 2008: Flying over storm-damaged refineries and chemical factories, a twin-engine plane carrying the ASPECT (Airborne Spectral Photometric Environmental Collection Technology) system has been on duty throughout the recent hurricanes that have swept the Florida and Gulf Coast areas. ASPECT is a project of the U.S. U.S. Environmental Protection Agencys National Decontamination Team. Los Alamos National Laboratory leads a science and technology program supporting the EPA and the ASPECT aircraft.
