Abstract
An exemplary beam alignment system uses beam sensors that generate electrical signals corresponding to an amount of beam striking each sensor. An offset correction circuit determines an amount of undesired beam striking the sensors. The offset correction circuit subtracts the undesired beam value from each of the electrical signals to generate respective corrected values. X and Y signals, generated based on the corrected values, determine an X-axis and Y-axis location of the beam on the beam sensors. Position control signals, generated based on the X and Y signals, control the position of the beam relative to the sensors resulting in a corresponding X-axis and Y-axis location of the beam on the sensors. This provides compensation for changes in orientation of the incoming beam relative to the sensors to maintain the beam location on the sensors.
