Abstract: A method and apparatus are described for improving the geometric fidelity of images reproduced in a charged particle beam device. The beam is deflected across a sensitive medium to form a test image of predetermined configuration. The test image is compared with a reference image and geometric deviations measured, at a number of points, are used to calculate correction signals required to modify the beam deflection to offset the deviations. Circuit adjustments are then made to provide the calculated correction signals. The correction signal adjustments are accomplished in separate non-interactive circuits for each of a plurality of predetermined corrections which only require a one time adjustment.

Abstract: An apparatus for recording an image onto a light recording medium (16) includes a light source (120) which emits light at a position which is movable over a light emitting area (21) of the light source controlled by a controller (13). A light position sensor (142) has a target area optically coupled to light emitted from a plurality of positions within the light emitting area of the light source used for recording for detecting the position of the light intersecting the target area of the sensor from the light emitting area of the light source and generating a signal dependent upon the light intersecting the target area. A controller (13), responsive to the signal, produces a correction parameter and controls the position of the light on the light emitting area of the light source with the correction parameter during recording. The present invention also reduces the effects of recording errors which occur near section boundaries as the sections are recorded onto a recording medium.
