Abrégé
(EN)
The present invention relates to a compact motorized rotational stage for microscopy applications and control methods for automated sample orientation/rotation. The rotational stage includes a motor, a rotational motion transmission mechanism, and a rotating sample holder for accommodating a holding device such as glass slides/Petri dishes of different sizes. Mouse embryos are used as an example to explain the control methods. A pattern recognition utility was developed for identifying mouse embryo structures. The transformation between the holding device rotational coordinate frame and the translational positioning stage coordinate frame is calibrated during image-based visual servo control. The polar body of an embryo is oriented through purely image-based visual servo control or through coordinate transformation and closed-loop position control.

La présente invention concerne un étage rotatif motorisé compact pour des applications de microscopie et des procédés de contrôle pour orienter ou faire tourner un échantillon de façon automatisée. L'étage rotatif comprend un moteur, un mécanisme de transmission de mouvement rotatif, et un porte-échantillon tournant destiné à loger un mécanisme de maintien tel que des lamelles et/ou boîtes de Pétri en verre de différentes tailles. Des embryons de souris sont utilisés comme exemple pour expliquer les procédés de contrôle. Un utilitaire de reconnaissance de motif a été développé pour identifier des structures d'embryon de souris. La transformation entre la fenêtre de coordonnée rotative du dispositif de maintien et la fenêtre de coordonnée d'étage de positionnement de translation est calibrée au cours d’une servocommande visuelle basée sur image. Le corps polaire d'un embryon est orienté par le biais de la servocommande visuelle basée sur image ou par le biais du contrôle de transformation de coordonnée et de position en boucle fermée.
