ABSTRACT:
A method of capturing images using a laser scanner equipped with a 2D micro actuator. The 2D micro actuator allows for laser beam location without the use of additional components dedicated to determining beam location. The 2D micro actuator is used to stabilize the positioning function of the spot in the scene. The micro actuator is a 1D micro actuator suspended within a second framework by two torsion bars and two pairs of orthogonal additional electrodes. The image is scanned, a precise rectangle of the character sensing field is generated and the image is created by keeping a substantially constant pitch.
