Abstract
The invention discloses a substituted light source device for graduating light intensity of a scintillator. The device comprises a shell, wherein a darkroom is formed in the shell; a PCB and a transmission fiber are arranged in the darkroom; a light-emitting circuit is arranged on the PCB, the light-emitting circuit comprises an input end, a current-limiting resistor and a light-emitting diode, the input end is connected to an external pulse generator, a first end of the current-limiting resistor is connected to the input end, a second end of the current-limiting resistor is connected to a negative electrode of the light-emitting diode, and a positive electrode of the light-emitting diode is grounded; the transmission fiber is connected to an external light intensity detector; and the light intensity of the light-emitting diode is adjusted by adjusting parameters of the pulse generator in order to graduate the light intensity detector. The light-emitting circuit is designed for the light-emitting diode, so that the light-emitting parameters of the light-emitting diode can be adjusted according to requirements. The light intensity of the light-emitting diode can be controlled by continuously changing the parameters of the pulse generator, and the light intensity detector can be graduated.
Description
technical field [0001] The invention relates to the technical field of scintillator radiation detection, in particular to an alternative light source device for marking the luminous intensity of a scintillator. Background technique [0002] Scintillator refers to a luminescent material that can emit light in the infrared, visible or ultraviolet bands when irradiated by a certain energy of rays. At present, radiation detectors based on scintillators are widely used in the fields of industry, medical treatment and basic scientific research, and are one of the most widely used methods in radiation detection. In the research and development of scintillators and the calibration of scintillator-based scintillator detectors, it is a very necessary work to understand the luminous intensity of materials and the response of photons in photoelectric conversion devices of detectors when they are irradiated. This requires an alternative light source with adjustable luminous intensity an...
