UNCOOLED THERMAL CAMERA AND ASSOCIATED PROCESS FOR INCREASING VIEWING EFFICIENCY

摘要

The invention relates to an uncooled thermal camera of the polarimetric type intended to increase day-time or night-time viewing efficiency. According to the invention, the thermal camera comprises a mount () for polarizing filters, some polarizing filters () with spectral transmission within the range of 3...12μm which are tiltable and mobile along two mutually perpendicular directions, an IR objective lens () with spectral transmission within the range of 8...12μm, a microbolometer detection array () with spectral transmission within the range of 8...12μm, some related electronic modules () for reading/playing on a display, a protective housing () for the objective lens () and the detection array () intended to provide uniform and constant temperature and a system () for fixing/positioning the system of polarizing filters () on the optical axis of the objective lens ().
