The invention provides a pulse X/gamma ray energy spectrum measurement device based on an optical fiber array and a method thereof. The device comprises a step-shaped or conical attenuation sheets with different thicknesses, a scintillator, an optical fiber array with different lengths, a photoelectric detector and a data acquisition system, wherein input ends of the attenuation sheet, the scintillator and the optical fiber array are arrayed in a ray incidence direction in sequence; a signal output end of a photoelectric device is connected with an input end of the data acquisition system through a signal cable; shield bodies are arranged between the photoelectric device and a ray source and between the photoelectric device and the data acquisition system; and a hole channel allowing optical fiber beams to pass through is arranged on each shield body. Through the device and the method, the energy spectrum measurement on single fast pulses, especially small-beam spot X/gamma rays can be fast realized; and the
