摘要

A phantom (28) for testing a time-resolved diffuse optical spectroscopy measuring apparatus, in particular a tissue oximeter, comprising: (a) input optics (30) having at least one light lead (32), (b) one behind a light flux direction at least a light supply line (32) arranged filter device (34) and (c) in the light flow direction behind the filter device (34) arranged light leads (40) which are arranged to the filter device (34), that for each of the light-discharges (40 ) the light detected by it is individually filterable by means of the filter device (34), and which are further merged to collect the light emerging from the filter device (34), so that upon illumination of the input optics (30) with an input light pulse (12) output Photons (16) emerge with a given photon time-of-flight distribution (22), (d) where the optical paths (w) are for light passing through different light-guides (40) is so different that an output pulse length of the photon-time distribution (22) is greater than an input pulse length of the input light pulse (12) and (e) wherein the light-discharges (40) and the filter device are formed in that a photon transit time distribution (22) corresponds to the photon transit time distribution caused by tissue (10).
