Real-time increase in depth of field of an uncooled thermal camera using several phase-mask technologies
Abstract : Imaging systems that combine a phase mask in the pupil and digital postprocessing mayhave better performance than conventional ones. We have built such a system to enhance the depth of field of an uncooled thermal camera. The phase masks are binary, their structures are optimized thanks to an image quality criterion, and they have been realized with three different technologies that give equivalent results. The deconvolution postprocessing is performed in real time with a graphics processing unit. A significant increase of the depth of field of a factor 3 has been obtained.
