Explanation
The travel (distance) on the paper is different between the light outputted from the exposure
center at the angle
θ
and further output light at the angle
θ
The travel (distance) on the
paper is different between the light outputted from the exposure center at the angle light at the
angle
θ
and further output light at the angle
θ
.(As shown in the illustration, length A, B).
The F
θ
lens changes the angle of diffracted light according to the angle of incoming beam, and
corrects the difference of travel (distance) on the paper.
