The present disclosure discloses a method and a system for imaging. The method for imaging objects using the system for imaging. The system for imaging comprises a lens. The objects comprise a first object, a second object and a third object located at different positions on a first preset track. The method for imaging comprises: allowing the lens and the first preset track to move relatively in a first predetermined relationship to acquire a clear image of the third object using the system for imaging without focusing, the first predetermined relationship is determined by a focal plane position of the first object and a focal plane position of the second object. The aforementioned method for imaging is high in imaging efficiency and is capable of fast focusing according to the first predetermined relationship even if focus tracking fails so that the blurring of a photographed image due to defocusing is avoided.

Imaging method, device and system

Disclosed are a positioning method, a positioning apparatus and a sequencing system (). The sequencing system () comprises an imaging assembly () and a mobile platform (), wherein the imaging assembly () comprises an optical axis (OP), the mobile platform () bears a reaction apparatus (), the stroke of the mobile platform () in a first direction is controlled by means of a limiting switch, and the stroke comprises a first limit. The method comprises the steps: (a) moving, by a first step distance, the mobile platform () in a direction approaching the first limit, until the distance between a current position of the reaction apparatus () and the previous position of the reaction apparatus () is less than the first step distance; (b) moving the mobile platform () in a direction that is the opposite of the moving direction in step (a); (c) moving the mobile platform () in the moving direction in step (a), until the mobile platform () reaches the first limit; and (d) moving, by a preset distance, the mobile platform () in the direction that is the opposite of the moving direction in step (a), so that the positions of the optical axis (OP) and the reaction apparatus () satisfy a preset relationship. According to the method, the quick and precise positioning of the mobile platform () can be realized by means of moving back and forth in the first direction, such that the positions of the optical axis (OP) and the reaction apparatus () satisfy a preset relationship.
