| Abstract: | The experimental method was built by transmission coefficient analysis to measure spectrum of narrow pulsed hard X-ray. The theoretical design of experiment plan was done and the data for spectrum unscrambling were obtained by simulation. The transmission coefficient was determined by measuring light intensity after attenuator, unfolded by the mathematical method of infinitesimal disturbance. The relative spectrum was reconstructed, and its reliability was validated. |
