Abstract

This study presents experimental results of a resolution enhancement algorithm used in the physical world without any microscan optomechanical element. The HR (High Resolution) software developed by Lightnics was used together with an uncooled microbolometer array from Ulis, with low thermal time constant. It takes advantage of the relative motion between camera and object to produce information redundancy through a set of captured images giving rise to one increased resolution image. Enhanced images from a bar target show better MTF and MRTD curves after HR software processing than before. In addition, lower spatial and temporal noises were obtained as an additional benefit of the algorithm.
