Methods The developed system adopting microcomputer control mode consisted of control software, communication circuit and mechanical driving. Visual Basic language was used to compile the system control software; AVR single chip microcontroller was used for carrying on the serial communication between upper computer and lower computer; and Solid Works software was applied to design the mechanical transmission structure and make objects. After the experimental platform was established, the functions and parameters of the proposed control system were tested. Results The examination parts where the analog light was projected on were monitored using camera system. All indexes of the proposed system met the requirements of clinical examination.Conclusion The control system can be used for clinical practical application or as a teaching instrument.
