IMAGE RECOGNITION BASE ABLATION PATTERN POSITION RECALL

摘要

Embodiments of the invention illustratively described herein generally include storing XYZ stage coordinates for the intended laser position, as well as a kernel image of the ablation pattern located during the scan positioning process, and where the laser is fired. It relates to comparing a current image of a current field of view of a camera/microscope comprising a kernel image. This comparison is used to correct for any built up errors during the course of the experiment. More specifically, an embodiment of the present invention relates to a software-based image recognition apparatus and method for correcting an error in an open loop system for positioning a sample with respect to a laser in an analysis system for dating zircon crystal grains.
