Paper Abstract
This work presents quantitative evaluation of errors in measurement
that arise in using a thermal imager as a radiometer. The analysis will
mainly deal with the 7 13 micron spectral region . The main sources
contributing to errors in spatial radiometric measurements can be
divided into three categories: 1) inaccuracies in determining
atmospheric transmittance and path radiance, 2) calibration errors and
dynamic range problems due to nonlinearities of instrument response,
3) errors due to spatial response arising from the finite point spread
function and non uniformities of the field of view.
The contribution of each of these factors to the final cumulative error
in the measured radiometric quantity will be analysed and the
sensitivity to the individual factors shown. This analysis is done with
respect to an existing measurement system in use, namely the AGEMA 780
Dual Band Thermovision Imager.
