EXPOSURE SYSTEM AND PRODUCTION METHOD FOR EXPOSURE SYSTEM

摘要

An exposure system storing a current value properly determined for supply to a light emitting element, and a production method for producing such an exposure system. The production method is characterized by comprising the steps of supplying a reference current to a light emitting element to respectively measure light quantities from a plurality of pixels of an optical modulation element, judging whether a minimum value of light quantities from the plurality of pixels falls within a predetermined range, and, if the minimum value does not fall within the range, determining a current value to be supplied to a light emitting element that allows the minimum value to fall within the range.
