<p>The device has a detecting unit (210) for detecting an image (200), and an illuminating unit (220) for producing diffused light. The illuminating unit has a light source (222) such as flash tube, which is arranged in such a manner that the light emitted from the light source is coupled and propagated into a light guiding unit (221). The guiding unit is made of a material with scattered particles in such a manner that the light propagated into the guiding unit is diffused and discharged into a surface area (223) of the guiding unit, where the surface area is turned towards the image.</p> |
