Contents

The aim of the project is to demonstrate the feasibility of a cheap and miniature ophthalmoscope based on versatile and portable MEMS scanning mirrors, capable of three-dimensional measurements of different structures of the fundus, including the optic nerve head, and functional measures requiring excitation. Such a device could be acquired by ophthalmologists, but also by general practice or paramedical staff (orthoptists, nurses and opticians) for the systematic and remote screening of glaucoma. This page describes the electronic system. For details about the optical system see TBD.

System

The proposed electronic system contains three main parts:

  • a controller
  • the mirror controller
  • the sensor data acquisition

TBD: schematic

Controller

The Controller is realized on a HEI FPGA-Rack FPGA board. This is a standard FPGA board used at HEI for various projects designed to fit in a 2U rack. The controlling is implemented in the Xilinx Spartan-6 LX FPGA. The USB connector is used to send the collected data on to a computer. On the other side, the VME 96 pin connects to other electronic components used for signal transformation.
