Structured Three-Dimensional Imaging Device with Reversible Image Guides

Abstract : The invention relates to an imaging device (E) comprising: at least one generator (1) of structured light; an emission first image guide (5, 5′) for uplinking the structured light from the generator (1) to an object to be observed; and a return second image guide (5′, 5) for downlinking the light reflected by said object to be observed to a system (2) for capturing said reflected light. Each of the two image guides (5, 5′) is able to uplink the structured light and downlink the reflected light, and the imaging device comprises an optical switch (3) configurable into three different operating modes.
