METHOD FOR OBSERVING BIOLOGICAL SPECIES

摘要

A method for observing biological species (CB) on a culture medium (MC) contained in a container having at least one translucent face (CP, BU), the method comprising the steps consisting of: a) directing a light beam (FL) onto one portion of said translucent face, so as to define at least one illuminated region (M1) and at least one non-illuminated region (MO) of said face; and b) acquiring an image of a portion (M2) of the surface of said culture medium illuminated by said light beam, the acquisition being carried out through said or at least one of said non-illuminated regions (MO) of said translucent face and along an optical acquisition axis forming a non-zero angle (a) with the direction of propagation of said light beam.
