We discuss the way to design electronic control in cerebral oximeter and extension module of confocal microscope. According to the need and application of the product, we determine the key parameters of this design, so that we can confirm the design scheme. During the design process, in the aspect of software design, we do software analysis and then code can be implemented. As to hardware, we additionally make simulation before design proof. In our final design of cerebral oximeter we've achieved LED's flexible control, including precise LED drive current control and independent multi-LED's high-speed encoding. In the design of confocal microscope's extension, we manage to make the microscope three dimension scan automatically. When designing, we should not always follow the traditional design, especially for the research use designs. In this kind of designs, flexibility may be more important than efficiency that traditional design always attach great importance to. |
