| 摘要 |
The invention concerns a method for observing a sample (12), the sample (12) comprising a set of organisms (14), a solid substrate (16) supporting the set of organisms (14). The method is characterised in that the method comprises the steps of illuminating at least one portion of the sample (12) by means of a light beam, acquiring a first diffraction pattern corresponding to a wave image resulting from the diffraction of the light beam by at least one portion of the set of organisms (14), acquiring a second diffraction pattern corresponding to a wave image resulting from the diffraction of the light beam by at least one portion of the sample (12), comparing the second diffraction pattern with the first diffraction pattern, and determining at least one characteristic relative to the set of organisms (14) from the result of the comparison step. |
