CONTROL WITH SERVO FEEDBACK BASED ON ALLOCATED SCANNING TRACKING BEAM IN DISPLAY SYSTEMS WITH SCANNING BEAMS AND LIGHT-EMITTING SCREENS

摘要

FIELD: physics.;SUBSTANCE: one tracking beam and excitation beam are turned on a screen which emits visible light when excited by light of the excitation beam, and optical matching of the excitation beam is controlled based on the position of the tracking beam on the screen through control with servo feedback.;EFFECT: controlling spatial matching of spatial positions of optical pulses in an excitation beam on a screen.;15 cl, 38 dwg
