| 摘要 |
The invention concerns a system, and its method of implementation, to determine the concentration of a substance mixed with a fluorophor and contained in one or more contacts of a matrix of contacts; it comprises:a microscope (1) associated with a magnifying objective lens (2) and with image acquisition means (4,5) to achieve a microscope image of the fluorescence of one of the contacts of the matrix or part of this contact;illumination means (11, 13) emitting a first beam to enable image acquisition in white light of said contact, and a second beam to excite the fluorophor contained in said contact;deflector means (15) for the second beam to ensure point by point scanning of the contact of the matrix;recording means (6, 7) to record the contact image; andprocessing means (6,7) of this image to quantify the fluorescence of the contact and determine the concentration of the substance.
