Development of high speed synchronous control system for real time 3D eye imaging equipment using deadbeat observer

데드비트 관측기를 이용한 망막의 3차원 실시간 영상화를 위한 고속 동기제어 시스템 개발

To show a retina shape and thickness on the computer monitor, a laser has been used in Scanning Laser Ophthalmoscope(SLO) equipment using the travelling difference. This method requires exact synchronous control of laser travelling in optic system to show a clear 3-dimensional image of retina. To obtain this image, this exact synchronism is very important for making the perfect plane scanning. In this study, a synchronous control of the galvanometer using deadbeat torque observer to make 3-dimensional retina image is presented. For the more, a very simple mathematical model of the galvanometer is approved by experimental result.
