THE SPECTRAL DISTRIBUTION OF THE THERMAL ENERGY RADIATED IN A FIRE IS
DETERMINED BY THE TEMPERATURE OF THE SOURCE (EMISSION) AND THE
COMPOSITION OF THE MEDIUM IT TRAVERSES (TRANSMISSION).  IN PRINCIPLE, 
THE CONDITIONS IN ANY ELEMENT OF THE REACTING VOLUME CAN BE DETERMINED
FROM ANALYSES OF THE CORRESPONDING INFRARED EMISSION AND TRANSMISSION
SPECTRA.  IN PRINCIPLE, THESE LOCAL SPECTRA CAN BE RECONSTRUCTED FROM
LINE-OF-SIGHT MEASUREMENTS USING STANDARD TOMOGRAPHIC ALGORITHMS.  THE
PURPOSE OF THIS TALK IS TO OUTLINE PLANS FOR THE DEVELOPMENT OF A FTIR
TOMOGRAPHIC SPECTROMETER WITH THE CAPABILITY TO MEASURE THE EMISSION
AND TRANSMISSION OF INFRARED RADIATION IN FIRES AS FUNCTIONS OF BOTH 
TIME AND SPACE.
