Abstract：With the development of the stroboscope technology, the calibration method of the speed standard device is gradually unable to meet the requirements in measuring accuracy and range. This paper introduces the principle and implementation of the calibrated stroboscope of the pulse frequency measurement method, and uses the photoelectric converter to convert the flash of the strobe to the frequency meter. The measurement errors obtained by using the frequency meter and the speed standard device are compared, and the calibration results have good consistency. An example of uncertainty of the measurement results of the calibrated stroboscope is given.
