Method for controlling exposure and scan-exposure apparatus

摘要

The present invention relates to a method for controlling exposure and a scan-exposure apparatus, which are used when a photosensitive material is scan-exposed. In the present invention, distance between a light source and a recording medium can be controlled on the basis of pre-measured distance correction data and timing at which light is emitted from the light source can be controlled on the basis of pre-measured light-emission correction data. Accordingly, it becomes possible to prevent the light beam irradiates the recording medium from going out of focus and to reduce the amount by which the position irradiated with the light beam deviates from a preset standard position.
