Abstract

The DSTO Primary Infrared Scene Projection (PIRSP) system has been used to investigate the practical application of the emitter array flood nonuniformity correction (NUC) technique. In the first instance the measurements have been limited to the special case of unity mapping ratio. The methods for achieving unity mapping at sub-pixel registration are described; in particular, the use of Moire fringes for accurately measuring the optical distortion across the field-of-view and for attaining the optimal mapping condition. Application of the flood NUC technique within the PIRSP system is discussed in terms of its convergence limitations. The latter include the presence of spatial and temporal camera noise, optical distortion, the mixing of neighbouring pixel information due to the finite point spread function and radiance-to-voltage transformation errors.
