Estimation of the configuration of an optical element for an optical writing device

摘要

A method and an device for estimating the configuration of an optical element for an optical writing device are disclosed. The optical characteristics of the optical element are estimated on the basis of configuration data derived from actual measurement. The estimated optical characteristics are used to estimate the performance of the optical element. The optical element has a sufficiently small curve on the image surface of the writing device ascribable to the shift of focal point.
