A device for imaging an interior of a turbid medium arranged to couple excitation light from a light source (5) into a receiving volume (20) containing a turbid medium from multiple entrance positions for light relative to the turbid medium (25) simultaneously. Multiple entrance positions for light may be created by coupling excitation light into the receiving volume (20) from M discrete entrance positions for light chosen from a plurality of N discrete entrance positions for light (M=N) or by coupling excitation light into the receiving volume (20) from multiple entrance positions for light with at least a subset of the multiple entrance positions for light forming a continuum.
