    摘要： One embodiment is directed to a system for geometric surface characterization, comprising: a deformable and controllably expandable transmissive layer coupled to a mounting structure and to an interface membrane; a first illumination source operatively coupled to the deformable transmissive layer and configured to emit first illumination light into the deformable transmissive layer at a known first illumination orientation; a detector configured to detect light from within at least a portion of the deformable transmissive layer; a computing system configured to operate the detector to detect at least a portion of light directed from the deformable transmissive layer, to determine surface orientations pertaining to positions along the interface membrane based at least in part upon interaction of the first illumination light with the deformable transmissive layer, and to utilize the determined surface orientations to characterize a geometric profile of the surface of the object as interfaced against the interface membrane.

    摘要： The invention discloses an optical imaging system and an imaging method regulated based on a spatial coherence structure, including the steps of: building a 4f imaging system; detecting, by a first optical detector, the shape of the spectrum domain obstacle in the 4f imaging system; designing a spatial coherence structure of the incident beam based on the shape of the spectrum domain obstacle, so that all the modes of the incident beam can pass through the opening in the obstacle; and placing an object to be detected in the optical path and detecting, by the second optical detector, the optical imaging information of the object to be detected. According to the present invention, in the case where the frequency plane of the 4f optical imaging system is partially occluded, imaging without speckles is enabled, utilization of the systematic light is substantially improved, and the signal-to-noise ratio in imaging is improved.
