Large-aperture MWIR Camera
Large-aperture MWIR Camera
Introduction
The detection component adopts self-adaptive multi-background and non-uniformity automatic correction technology, and intelligent image processing algorithm with image noise filtering, image enhancement, and automatic light adjustment to ensures high-sensitivity and high-sharpness video images. It also adopts technology of vibration resistance, high and low temperature resistance, and sealing package to ensure high reliability and good sealing performance. It can be applied to photoelectric theodolites, photoelectric turrets and other high frame rate (≥100Hz) that can be customized.
Features
—Transmission-type and large-caliber zooming MWIR Camera
—It can operate for long distance, the ranging on people can reach over 12Km, on targets can reach over 1000Km.
—With high stability of the optical axis it can achieve stable switching of the field of view within 2 pixels ranging.
Application
Long-distance detection, identification and tracking for small targets
