ABSTRACT:
Adaptive correction techniques are disclosed that adaptively correct aberrations which may arise in systems such as laser printers, for example. For laser printers, calibration data processing results may be detected by a detector that is disposed to correspond physically to the recording medium so that characteristics such as position and intensity of a laser beam at the detector corresponds to that of a laser beam at the recording medium. In this way, aberrations in system performance may be adaptively corrected while the system is performing operational processes.
