Ghost fiber optic 3d endoscopy

A new type of ghost fiber optic endoscopy has been proposed to obtain ghost images of three-dimensional optically transparent objects. The method is based on spatial and temporal correlation of light beams formed in a bundle of single-mode fibers exposed in the transverse direction to femtosecond laser pulses. Resolution in the depth of an object is ensured by an original algorithm to reconstruct images, which involves both the properties of femtosecond radiation and the features of light propagation in an inhomogeneous scattering medium. The effectiveness of the proposed method has been confirmed by a numerical simulation by an example of an octahedron with a layered structure.
