| 摘要 |
The invention concerns an apparatus for automatic reading of an antibiogram, said apparatus comprising an illumination system for illuminating a Petri dish (B) containing antibiotic lozenges positioned on a culture medium seeded with a germ, and an electronic CDD camera (3) for acquiring images of the antibiogram. The invention is characterised in that the illuminating system comprises illuminating means (6) for focusing the optical beams towards the dish surface, the incident beams forming an oblique angle ( alpha ) relatively to the surface of the dish (B) to be illuminated, such that the reflected rays pass in the proximity of the camera lens (3), without, however, penetrating therein, to optimise the image contrasts.
