| Abstract: | A new frequency track signal processing circuit that was used for laser Doppler velometer experimental system had been designed and presented in this paper. With this signal processing circuit we realized the real time measurement of the flow velocity by laser Doppler system which had the advantages of simple, reliability and easy to operate by students. |
