An Image Stabilization Optical System Using Deformable Freeform Mirrors

“…This is achieved by sensing the angular positions about its center of rotation with an inertial sensor when the host platform or a pointing mirror in the system undergoes disturbances, or by calculating the image sequence interframe offset with image processing techniques [ 1 – 4 ]. Then it is stabilized by generating the necessary counter-rotations with the spin and torquer motors [ 5 – 12 ] which necessitates larger moment of inertia resulting in a large system and a slow response rate. Thus a combined servo mechanism and stabilization frame are generally suggested in the systems to achieve a stabilization accuracy of 0.10 mrad without increase of the volume [ 13 – 15 ], e.g., the coarse/fine combination two-level stabilization technique in helicopters, the two-axis line-of-sight stabilization system mounted on a stabilized platform for vehicle navigation, and etc .…”

Color-based video stabilization for real-time on-board object detection on high-speed trains

“…Their performance degrades with vibration in the critical 0 -20 Hz range [2]. However, the introduction of real-time electronic image stabilization systems in this field is becoming prevalent [3] because the software system allows to reduce the equipment cost. By this time many electronic stabilization systems have been realized but best results are obtained in post processing mode (not in real time).…”
