This variant of the Dual-Channel Image Tracking system is designed for applications where minimal weight, high agility, and maximum acceleration capability are essential. Two image sensors—typically for visible and infrared light—are rotated synchronously around two parallel axes to compensate for platform motion. Each sensor can additionally be adjusted linearly in its viewing direction, enabling stable image alignment even during rapid maneuvers or target transitions.

Advantages of piezomotor concept

Unlike the standard version, this system relies entirely on piezo motor technology: Both rotation and linear motion are implemented using precise, high-response piezo actuators. The highly compact design enables extreme accelerations and short response times—ideal for deployment on UAVs, reconnaissance aircraft, or mobile ISR platforms requiring high dynamic performance.
To further reduce system weight, structural components can be manufactured in PEEK or magnesium. These materials offer excellent mechanical strength-to-weight ratios and are well-suited for airborne ISR applications.

Synchronous rotation of the sensor mounts is achieved via two independently supported piezo actuators using a cable-driven mechanism. The high resolution and backlash-free performance of this drive principle ensures precise image tracking under dynamic conditions. The independent linear axes reach accelerations of up to 22 m/s² with sub-micron repeatability. High-resolution optical encoders ensure accurate and stable position control across all operating scenarios.
