Claim Text:
1. A laser alignment device with a movable mirror, comprising: an image acquisition means for collecting incident laser to form an image; a moveable mirror for reflecting the laser to the image acquisition means and blocking the laser to be directly irradiated to a target; and a lens which is located between the target and the image acquisition means and used to form an image of the target in the image acquisition means, wherein the movable mirror is operable to move linearly with respect to the image acquisition means in a direction perpendicular to the image acquisition means, and wherein the movable mirror is driven in the perpendicular direction by a servo driving system for a plurality of times to different positions so that (a) a relative distance between the movable mirror and the image acquisition means is dynamically adjusted for different sections of the target and (b) an image is formed at the image acquisition means at each position, and wherein a pitch angle of the laser reflected onto the image acquisition means is adjusted for at least one position of the movable mirror to form an image at another point thereon to optimize energy distribution of the laser.
