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

To show a retina shape and thickness on the computer monitor, a laser has been used in scanning laser ophthalmoscope (SLO) equipment using the traveling difference of the laser. This method requires exact synchronous control of laser traveling 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 to make 3-dimensional retina image is presented. For the more, a very simple mathematical model of the galvanometer is approved by experimental result.
