Continuous Zoom IR Thermal Imager With Multiple Scanning Modes
Product Introduction
Continuous zoom IR thermal imager with multiple scanning modes adopts high precision, fast response and scanning system for closed-loop control to compensate the image motion generated by continuous rotation of the turret. After the turret or scanning platform rotates one round, the equipment can scan and alert the targets within 360°. When suspicious targets are identified, the device switches to the tracking mode by following the system instructions or control strategies. The device is widely used for high-precision photoelectric search system and integrated search-tracking photoelectric system.
Product Features
· Folded optical path design, compact and small;
· Large/medium/small FOV scanning-back design;
· Image enhancement, automatic dimming, noise filtering and other intelligent image processing algorithms.
