2. Abstract המעבדה למערכות ספרתיות מהירות High speed digital systems laboratory 2 The project is a collaboration between the Physics Adaptive Optics Lab and HS DSL. Developing a system that controls adaptive mirrors, by changing the voltage of their capacitors (up to 124 capacitors). The system will eventually be integrated into an optical device that present the image of the retina (the back of the eye). During this process the device will also fix the distortion of the picture that reflected by the cornea.
