TALBOT-ILLUMINATED IMAGING DEVICES, SYSTEMS, AND METHODS FOR FOCAL PLANE TUNING

摘要

A Talbot-illuminated imaging system for focal plane tuning, the device comprising a Talbot element, a tunable illumination source, a scanning mechanism, a light detector, and a processor. The element generate scan array of focused light spots at a focal plane. The tunable illumination source shifts the focal plane to a plane of interest by adjusting a wavelength of light incident the Talbot element. The scanning mechanism scans an object across an array of focused light spots in a scanning direction. The light detector determines time-varying light data associated with the array of focused light spots as the object scans across the array of light spots. The processor constructs an image of the object based on the time-varying data.
