Beschreibung
Zusammenfassung:	Embodiments of the present invention provide an apparatus for determining spectral information of a three-dimensional object, comprising a cavity (110) for location in relation to the object, an imaging light source (120) located in relation to the cavity, wherein the imaging source is controllable to selectively emit light in a plurality of wavelength ranges, structured light source (130) for emitting structured illumination toward the object, wherein the structured light source comprises a plurality of illumination devices arranged around the cavity, one or more imaging devices (140) for generating image data relating to at least a portion of the object, a control unit, wherein the control unit (1100) is arranged to control the structured light source to emit the structured illumination and to control the imaging light source to emit light in a selected one or more of the plurality of wavelength ranges, a data storage unit (1120) arranged to store image data corresponding to the structured illumination and each of the selected one or more of the plurality of wavelength ranges, and processing means (1110) arranged to determine depth information relating to at least a portion of the object in dependence on the image data corresponding to the structured illumination stored in the data storage means.
