According to one aspect, the invention relates to a device (200) for transporting and controlling light beams comprising a light guide (40) comprising a packet (50) of uncoupled single-mode optical fibers (Fi), each single-mode optical fiber ( Fi) being intended to receive an elementary light beam (B1i) at a proximal end and to emit a light beam (B2i) at a distal end, said packet of single-mode optical fibers comprising, in operation, a minimum radius of curvature corresponding to a maximum curvature of the bundle of fibers. The device (200) further comprises an optical phase control device arranged on the side of the proximal end of the light guide (40) comprising at least a first spatial light modulator (30) suitable for the application of a phase shift on each of the elementary beams (Bu) and a control unit (60) of the first spatial light modulator configured to apply a phase shift on each of the elementary beams (Bu) to form a beam at the distal end of the light guide of illumination with a predetermined phase function. According to the present description, said packet (50) of single-mode optical fibers is twisted, and includes a twist period (P) determined to maintain said phase function at the distal end of the light guide when the packet of single-mode optical fibers is subjected a curvature less than said maximum curvature. Selon un aspect, l'invention concerne un dispositif (200) de transport et de contrôle de faisceaux lumineux comprenant un guide de lumière (40) comprenant un paquet (50) de fibres optiques monomodes (Fi) non couplées, chaque fibre optique monomode (Fi) étant destinée à recevoir un faisceau lumineux élémentaire (B1i) à une extrémité proximale et à émettre un faisceau lumineux (B2i) à une extrémité distale, ledit paquet de fibres optiques monomodes comprenant, en opération, un rayon de courbure minimal correspondant à une courbure maximale du paquet de fibres. Le dispositif (200) comprend en outre un dispositif optique de contrôle de l
