Abstract：A synchronous rotating speed sensor for optical fiber rotating mirror high-speed camera is designed.A high accuracy digital measurement method is proposed by combining micro control unit (MCU ) and complex programmable logic device (CPLD ).MCU and CPLD communicate through serial peripheral interface (SPI),and MCU transfers the corresponding spark base delay and pulse width to CPLD.The detection signal is sent to CPLD for filtering and counting processing after enlarging and shaping.CPLD sends the measured data to the computer by serial port to the computer for real-time display, and simultaneously outputs the synchronous control signal.The test data show that the relative error of the time measurement is less than ± 0.2%.The error of the imaging system is about 4.5 mm, and the drift time is about 3μs,which meets the requirements of the experiment.
