Patent number: 9575307Abstract: Compressive sensing based video rate imaging techniques are presented. Rather than scan the entire image, the imaging system only scans part of the topography of the sample as a compressed scan. After the data has been collected, an algorithm for image reconstruction is applied for recovering the image. Because compressive sensing is used, the imaging rate is increased from several minutes per frame to seconds per frame. Non-vector space control techniques are also presented. No-vector space control use image or compressive data as the input and feedback to generate a closed-loop motion control. Compressive sensing technique provides an efficient data reduction method to retain the essential information in the original image. The non-vector space control method can be used as motion control method with compressive feedback without or with noise.Type: GrantFiled: March 15, 2013Date of Patent: February 21, 2017Assignee: Board of Trustees of Michigan State UniversityInventors: Ning Xi, Bo Song, Jianguo Zhao, Wai Chiu King Lai
