The Blondel-Rey method of effective light intensity spatial distribution for pulsed light source was studied. The measurement of instantaneous light intensity was realized by adopting the composite trapezium numerical integration, and the spectral mismatch correction of high color temperature light source measurement was analyzed. Based on the principle of double-reflector synchronous measurement, a measuring device of effective light intensity spatial distribution for pulsed light source was established. The key components such as whole space distributed rotating platform, pulsed light intensity detection system and high resolution spectrometer for spectral mismatch correction were analyzed in detail. And the measuring device was calibrated by using the high color temperature modulation light source. Finally, the measurement uncertainty of this measuring device was analyzed, and the expanded uncertainty could reach to 3.0%.
