Abstract: A system includes a plurality of actuators configured to provide forces to an actuatable member to actuate the member between a first position and a second position during an actuation mode. The actuators are also configured to return the member from the second position to the first position during a retrace mode. The system also includes a controller configured to control the actuators. The controller is configured to identify a back electromotive force (BEMF) of each of the actuators during the retrace mode. The controller is also configured to responsively provide control signals to drive the actuators such that the forces provided by the actuators to the member during the actuation mode are substantially equal.
Abstract translation: 一种系统包括多个致动器，其构造成在致动模式期间向可致动构件提供力以致动构件在第一位置和第二位置之间。 致动器还构造成在回扫模式期间将构件从第二位置返回到第一位置。 该系统还包括被配置为控制致动器的控制器。 控制器被配置为在回扫模式期间识别每个致动器的反电动势（BEMF）。 控制器还被配置为响应地提供控制信号以驱动致动器，使得在致动模式期间由致动器提供给构件的力基本相等。

Abstract: A dual-field-of-view (FOV) optical imaging system having a primary FOV and a simultaneously viewable secondary FOV. One example of the system includes an imaging sensor, primary and secondary FOV objective optics configured to receive and output electromagnetic radiation corresponding to the primary FOV and secondary FOV, respectively, imager optics, and a field-of-view selection mechanism disposed between the secondary FOV objective optics and the imager optics and configured to selectively pass the second FOV to the imager optics, the imaging sensor being configured to produce primary FOV image frames and combined image frames that include imagery from both the primary and secondary fields-of-view.

Abstract: A system, and method of operating the same detects moving targets in images and performs image turbulence correction. The system includes an automatic target recognizer (ATR) system including a database. The ATR includes a feature extractor and processor arranged to detect a plurality of reference features associated with targets within image frames, and calculate a position of the plurality of reference features. The system includes an image processor arranged to receive the position, demosaic the image frames into a plurality of video tiles, iteratively process the video tiles for turbulence correction to generate turbulence corrected video tiles associated with acquired targets; convert the turbulence corrected video tiles into a single video frame tile including turbulence degradation correction; and mosaic each of the single video frame tiles to generate a full field of view turbulence corrected video stream.
