Patent attributes
Confocal optical scanning device designed to allow visualization of an object to be observed (1107) and comprising:an optical system designed, on the one hand, to focus an illuminating beam (FX) coming from a light source on to at least one illuminating point (FXO) intended to illuminate a point of the object to be observed (1107) and, on the other hand, to focus a light beam (FE) coming from the illuminated point of the object (1107) on to a luminous point (FEO) in a first image plane (P1),at least one rotatably mounted mobile mirror (1104) on which are reflected, on the one hand, the illuminating beam (FX) to allow the scanning of the object to be observed (1107) along an observed plane and, on the other hand, the light beam (FE) to bring the luminous point (FEO) on to a fixed point on the first image plane,a first spatial filtering system (1203) arranged in the first image plane and designed to filter the luminous point (FEO) to obtain a beam to be detected (FD).
