Abstract
Example devices and methods for visualization and three-dimensional reconstruction of an area of interest are disclosed. An example device includes a first light source able to send quasi-monochromatic light through a monomode optical fibre and a second light source able to send light through a set of optical fibres. The example device also includes a diffractive element that induces a pattern to be projected on an area of interest when the first light source is switched on. In addition, the example device includes a camera that has a spatiotemporal resolution such that it is able to visualize the pattern created by the first light source and the area of interest illuminated by the second light source that appears uniformly illuminated even if diffractive element covers at least partially the second cross-section of the set of optical fibres.
