Title:
POSITION ADJUSTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/080048
Kind Code:
A1
Abstract:
According to the present invention, visual feedback control is performed stably and appropriately even if vibration occurs in a target object. A position adjusting device (1) comprises an installation unit, a stage servo circuit (131), an acceleration sensor (14), a vibration processing unit (124), and a signal generating unit (12). A target object is installed on the installation unit. The stage servo circuit (131) drives the installation unit to change the position of the target object. The acceleration sensor (14) detects vibrations of the target object. The vibration processing unit (124) detects a period of the vibrations on the basis of a detection signal from the acceleration sensor (14). In visual feedback control for moving the target object to a target position, the signal generating unit (12) acquires captured images, at an acquisition timing based on the period of the vibrations, from a camera (11) for imaging the target object, generates control signals for moving the target object to the target position, from each acquired captured image, and successively outputs the generated control signals to a drive unit.
