TALBOT IMAGING DEVICES AND SYSTEMS

摘要

A Talbot imaging system comprising a Talbot element, a phase gradient generating device, a light detector, and a processor. The Talbot element repeats a Talbot image at a distance from the Talbot element. The phase gradient generating device scans the Talbot image at a plane at the distance from the Talbot element by incrementally changing a phase gradient of a light field incident the Talbot element. As the Talbot image is scanned, the light detector captures time varying data associated with light altered by an object located at the distance from the Talbot element. The processor reconstructs an image of the object based on the time-varying light data.
