Abstract
This paper presents the image quality issues encountered at system level when working with infrared imagers. This work highlights some characteristics that are usually not specified for off-theshelf components. The first part of this work discusses the need for short-term and long-term stability. We present a comparative study of two sensors in the MW band based on the residual fixed pattern noise and defective pixels. In the second part we present the issues of patterns defects. We conduct an experimental study on twelve persons to estimate the perception threshold of such defects within an infrared sequence.
