Abstract :
In this study, we present an integration scheme of preprocessing circuit for detecting optical pulse based FPGA-tech. Using the photoelectric detection technique, the scheme includes a the photodiode detector (PDD), which can convert an optical pulse to a small current signal; and a FPGA produces code to control MUXes for different channel, which changes circuit parameters to adapt different detection situation. Design issues are addressed. Testing circuits are implemented. Simulation wave displayed on the oscillograph and the data of the system acquiring are presented. And the feasibility of the scheme is confirmed by the data analyse. Presently, the scheme has been used in a lightning detection system.
