Abstract: An imaging system (100) comprises a multimode waveguide (Wm) configured to receive input light (Li) from a light source (20) into its proximal side (13p) and output a corresponding speckle pattern (Pn) based on the input light (Li) out of its distal side (13d) for illuminating a sample (S) to be imaged. A single-mode waveguide (Ws) is connected to the multimode waveguide (Wm) for coupling the input light (Li) from the light source (20) to the multimode waveguide (Wm). The multimode waveguide (Wm) has a relatively short length (Zm) and relatively high flexural rigidity (R) for maintaining a unique relation between the input characteristic (λ,A) of the input light (Li) into the multimode waveguide (Wm) and a spatial distribution (Ixy) of the speckle pattern (Pn). The single-mode waveguide (Ws) may be relatively long and flexible (F) for allowing movement of the short rigid multimode waveguide (Wm).
