Paper Abstract

A computational prototyping environment has been developed for the chemical imaging sensor, an IR imaging passive standoff detection device based on the rapid-scan Fourier transform interferometer. The environment uses commercially available software (AVS) which features a visual programing interface, extensive visualization capabilities, interactive steering, and an ability to distribute computations over a heterogenous group of computers. Physical models developed to simulate device behavior are incorporated into AVS modules and data-flow networks. The main distinctions of the models are the use of a ray tracing algorithm in the simulations of interference in the optical system and the application of the radiometric model of MODTRAN for realistic simulations of atmospheric transmittance and radiance. The simulations predict abilities of the device to measure interferograms and spectra as well as spectral images of clouds containing harmful chemicals.
