Abstract

The reasons of angular non-linearity in 2-D optical scanner are analyzed.Equations of angular of elevation,azimuth and vertical in 2-D scanning are demonstrated.Scanning non-linearity is analyzed.Its influence on angular tracking and scanning imaging is discussed.Method of correction is pointed out.
