12-micron stand-alone thermal image sensor for handheld cameras
Atto320 brings sharply focused and accurate images, compactness and extended battery-life to handheld camera makers. The advantage of offering Atto320 as a stand-alone component is that system integrators have flexibility in configuring designs that meet their specific performance needs, enabling them to offer true product differentiation to end-users. Alternative 12-micron products often come, ULIS says, either as modules or thermal camera cores, where access to the thermal image sensor’s performance parameters is restricted.
The fully digital Atto320, a 320×240 thermal image sensor (microbolometer), is designed with ULIS’ 12-micron technology for sensor miniaturization. It generates high-quality moving images due to the high frame rate (60 Hz) and ease-of-use handling with simple calibration. These features allow users to view fast-moving objects as well as observe scenes at distances of several hundred metres. The sensor consumes less than 220 mW at 60 Hz, enabling extended autonomy of more than 10 hours for handheld systems.
Atto320 can reduce the size of the optics by as much as 50%, translating to a cost reduction of up to 20%. It is fully compatible with other ULIS products in its 17-micron GEN2 imaging sensor line. It offers advanced performance in temperature difference detection, as low as 0.06°C (60mK thermal sensitivity).
