Abstract:
System for determining the alignment of an object, whose image is to be recorded, with a coupling eyepiece and an image capture apparatus that defines an image plane (Pi), characterized in that it comprises:an image capture apparatus (2) equipped with means for adjusting its own position;coupling eyepiece means (3) that focus on an object plane (Po) and that ensure the coupling of an image in the image plane with an image created in the object plane;a light source (1) that is movable in the object plane and that emits at least two non-focused luminous dots (1a, 1b);a removable opaque mask (4) that is perforated with at least two holes (5a, 5b) and that is positioned in front of light source (1) such that it transmits at least part of the light emitted by said light source, the light transmitted through each hole in the mask forming at least one image (2a, 2b) of a luminous dot on the capture apparatus, said at least one image being split into two if the elements are non-aligned, andmeans for determining whether alignment exists and, in the case of non-alignment, for quantifying said non-alignment.
