Abstract
One embodiment is directed to a system for characterizing interaction between surfaces, comprising: a deformable transmissive layer coupled to an interface membrane, wherein the interface membrane is interfaced against at least one aspect of an interfaced object; 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 relative to the deformable transmissive layer, such that at least a portion of the first illumination light interacts with the deformable transmissive layer; a detector configured to detect light from within at least a portion of the deformable transmissive layer; and 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 at least one aspect…
