ABSTRACT:
A system for the automatic observation and quantification of phenomena capable of being detected by fluorescence and appearing in a localized zone (8), the system comprising a source of radiation (2), optionally associated with an excitation filter (5) to send on the localized zone (8) an excitation radiation capable of producing the fluorescence, optical observation means (7) of the localized zone (8) and at least one filter (12) intended to block the excitation radiation and arranged in the path of the luminous radiation of fluorescence emanating from the localized zone (8). In accordance with the invention, the localized zone (8) is observed by a picture-taking tube (17) and through colored filters or windows on a disc (18) intercepting beam 11. The sucessive colored images are memorized and then read simultaneously.
