Abstract (en)
[origin: WO2016097191A1] According to one aspect, the invention relates to a device for transporting and controlling light pulses for lensless endo-microscopic imaging and comprises: a bundle of N monomode optical fibres (Fi) arranged in a given pattern, each monomode optical fibre being characterized by a relative group delay value (Ax) defined relative to the trip time of a pulse propagating in a reference monomode optical fibre (F 0) of the bundle of fibres (40); an optical device (50) for controlling group speed, comprising a given number M of half-wave plates (P j) that are characterized by a given delay (8t j); a first spatial light modulator (51) suitable for forming from an incident light beam a number N of elementary light beams (B i) each of which is intended to enter into one of said optical fibres, each elementary beam being intended to pass into a given half-wave plate such that the sum of the delay introduced by said half-wave plate and the relative group delay of the optical fibre intended to receive said elementary light beam is minimal in absolute value; a second spatial light modulator (52) suitable for deviating each of the N elementary light beams such that each elementary light beam penetrates into the corresponding optical fibre perpendicularly to the entrance face of the optical fibre.
