Design And Realization Of Synoptophore For The Diagnosis And Treatment Of Strabismus And Amblyopia

Synoptophore is a clinical and basic theory of visual and eyeball movement physiology Comprehensive instrument which is also called as Large instrument for amblyopia, amblyscope or heteroscope, that can not noly be used in check and diagnosis amblyopia and strabismus,but also be used in the Clinical treatment.This subject originated from the new type synoptophore that independently projected and developed by the company which based on the market demand. By study the project, the synoptophore’s motion mechanism, control circuit and The appearance of the product have been optimized which get more advantageous for the product in the market competition.In this article which is based on the physiological characteristics of hunman eyeball, mainly study on the motion mechanism and voice photoelectric controlled system which are adapted to the diagnosis and treatment of strabismus and amblyopia. According to the form of the movement of human eye, the movement mechanism was independently designed by three shafts:This design take the human eyeball as the rotating center of the right and the left optical lens barrels which can achieve six degrees of freedom movement driveed by the connecting parts, including the pitching、the internal and external rotation、 the self rotation the displacement of three shafts and so on, which can meet the accuracy of quantitative measurement data and clinical training about strabismus.Base on FPGA has the ability to programme large scale device for design time and control circuit of synoptophore, namely, for the purpose of simplifying the circuit and improving the timing accuracy, in stead of the traditional 555 chip and its simulated Resonant circuit formed by peripheral circuits, we use the timing pulse which provided by the quartz crystal resonator to achieve the timing circuit.Through the programming of FPGA to achieve the control of time timing, display and sound and light alarm.
