Abstract: In many applications such as automobiles on busy highways, if a lot of vehicles on road are equipped with Doppler radars to help improve driving safety, no matter human-driven or auto-driven, if the radars use same frequency band, avoiding interference between them is a hard task. Assigning distinct frequencies is one of the solutions, however not only it wastes expensive spectrum resource, but also the task itself to dynamically assign frequency to vehicles randomly come together becomes a hard one to do. The disclosed invention of Doppler group radar will allow radar devices to work together using shared frequency band without interfering one another, without sacrificing performance, and without much increase in costs.

Abstract: In many applications such as automobiles on busy highways, if a lot of vehicles on road are equipped with Doppler LIDARs to help improve driving safety, no matter human-driven or autonomous-driven, when multiple LIDARs are simultaneously illuminating an object, the LIDARs signals will interfere with each other. Avoiding interference between them is a hard task. The disclosed invention of “Doppler group LIDAR” will allow LIDAR devices of this kind to inherently work together in “physical layer” without interfering one another, without sacrificing performance, and without having to rely on higher layer protocols to achieve these goals, so that all LIDARs of this kind interoperate easily and reliably.

Abstract: A CT device and method based on motion compensation are proposed. The present invention obtains motion parameters of a target object by using a stereo-vision-based motion measurement system, and then implements motion compensation through the technology based on reconstructed image matrix transformation, thereby obtaining a clear 2D/3D CT image while eliminating motion artifacts. The present invention can effectively eliminate motion artifacts caused by the scanned object's own motions in the CT scanning, and can be easily embedded into the existing CT scanning equipments. The present invention can improve quality of the CT images, and is especially important for CT imaging of some special groups of people that can not control their own motions, such as Parkinson's patients, infants, living mouse and so on. It can also improve ultra-high-resolution imaging of human body.
