Direct galvanometer correction system

The utility model is suitable for the field of galvanometer correction in the laser processing technology, and provides a direct type galvanometer correction system, which comprises a galvanometer control module, a galvanometer scanning module, a CCD (Charge Coupled Device) image acquisition device, a CCD image processing module and a correction processing module. According to the utility model, the laser is directly imaged on the CCD image acquisition device, so that the error caused by non-uniform burning of the laser on the correction plate is eliminated. An external light source is not needed, and errors caused by instability of the external light source are eliminated. The device is simple and stable in structure and free of moving parts, and motor motion errors of single-point acquisition are eliminated. 本实用新型适用于激光加工技术振镜校正领域，提供了一种直接式振镜校正系统，包括：振镜控制模块，振镜扫描模块，CCD图像采集装置，CCD图像处理模块和校正处理模块。本实用新型通过激光在直接在CCD图像采集装置上成像，消除了激光在校正板上灼烧不均匀导致的误差。无需外部光源，消除了外部光源不稳定导致的误差。本实用新型结构简单、稳定且无运动部件，消除了单点采集的电机运动误差。
