    摘要: An electro-optical system for adjusting beam to beam intensity non-uniformity in a multi-beam scanning system is disclosed. The electro-optical system consists of N×M array of light beams and N×M array of photodetectors wherein optical means deflect the light beams onto the photodetector array. A circuit consisting of N×M array of programmable laser drivers for each light beam and having an N×M array of feedback loops is used to adjust an intensity of each beam through the programmable laser drivers wherein each programmable laser driver uses the photodetector array as a reference source to correct for beam to beam uniformity correction.

    摘要: Uniformity of light output from an LED printbar is achieved by current sensing or image sensing of auxiliary LEDs on the LED printbar. A photodetector measures the light output from the auxiliary LEDs and a comparator will compare the auxiliary LED data to determine if the entire LED printbar has to be compensated to make the light output more uniform.
