The multi-gear MWIR thermal imager is mainly composed of a front telescopic system module, a high-performance swingscan mirror, and a relay combined high-sensitivity imaging detector module.The two types of lenses have focal lengths of 60mm~360mm (640×512@15μm, F4.0) and 50mm~500mm (640×512@25μm, F2.0) respectively. They adopt compact optical structure and precision mechanical structure design, with component integration realized through later visual assembly and adjustment technology and advanced servo control technology. To achieve tracking under NFOV and rapid search and capture of targets under WFOV, the thermal imager adopts three optical systems with WFOV, MFOV and NFOV for wide-area search, meeting the requirement of continuous FOV change for image tracking. It uses swing-scan mirror retrace technology combined with image stitching and reconstruction technology to eliminate image blurring. In the omnidirectional rapid circular scanning mode, it ensures image clarity and continuity during rapid azimuth rotation, enabling search, scanning and alerting of targets within the surrounding 360° range.

The equipment is widely used in infrared search/tracking optoelectronic systems, enabling the systems to perform 360° omnidirectional rapid search and target tracking measurement in the surveillance area.

• The swing-scan mirror retrace technology ensures clear and continuous target images during rapid azimuth rotation.

• Support circular scanning imaging and staring imaging modes.

• Three FOV available under circular scanning imaging mode.

• With continuous zoom and multi FOV switching , clear images throughout the switching process under staring imaging mode.
