Conventional methods for near-field scanning microscopy of test specimens in liquid assume the presence of a sufficiently smooth, reflecting specimen surface for detecting the vibrating movement of the optical fiber tip, and thus for controlling the distance between the tip and surface. Any desired specimens can be investigated in virtually any liquid by means of the method according to the invention, in which the vibrating movement is detected without reflection at the specimen surface, preferably with the aid of a light beam extending largely parallel to the specimen surface. Investigation of changes caused on the specimen surface by the liquid.

Avec les méthodes traditionnelles de microscopie à balayage en champ proche de prélèvements dans du liquide, on suppose que la surface réfléchissante de prélèvement est suffisamment lisse pour détecter le mouvement vibratoire de la pointe de la fibre optique et régler la distance entre la pointe et la surface. Tout prélèvement peut être examiné dans à peu près n'importe quel liquide grâce à la méthode visée par la présente invention, selon laquelle le mouvement vibratoire peut être détecté sans réflexion sur la surface de prélèvement, de préférence à l'aide d'un faisceau lumineux diffusé en grande partie parallèlement à la surface de prélèvement. On peut en outre examiner les changements sur la surface de prélèvement qui sont causés par le liquide.
