The invention provides a device and method for determining the flicker frequency of a radiation wave source. The device comprises a detection gyroscope and a control box; a control unit and a motor for driving the detection gyroscope to rotate are arranged in the control box, and a rotating shaft of the motor is connected with a rotating shaft of the detection gyroscope; the detection gyroscope comprises a rotating disc, a fan section is arranged on the upper disc face of the rotating disc, a strong absorbing medium for radiation waves is adopted as a surface layer material of the upper disc surface, and a weak absorbing and scattering medium for the radiation waves is adopted as a surface layer material of the fan section; and a rotating speed detection unit is installed on the lower surface of the rotating disc and connected with the control unit. Fourier transform for transforming time information of the radiation wave source into space information is achieved by means of fan spokesrotating at a high speed, the test precision of the flicker frequency of the radiation wave source can be effectively improved, the device is suitable for flicker frequency determination of multiplevisible or invisible radiation wave sources including sunlight, and the precision upper limit of the device can be improved by 100 times or above. The device has the advantages that operation is easy,to-be-detected radiation wave sources are not limited, and the application prospect is wide.
Description
technical field [0001] The present application relates to the technical field of measuring the frequency of radiation wave sources, in particular to a device and method for measuring the scintillation frequency of radiation wave sources. Background technique [0002] The flickering of the radiation wave source means that the radiation wave emitted by the radiation wave source changes rapidly and repeatedly over time, making the radiation wave source beating and unstable. Taking the common light source in daily life as an example, in addition to intermittent changes in the light source flickering, there are also periodic changes in the frequency, intensity, and certain sub-item physical parameters of light, which are all light source flickering . Of course, the human naked eye cannot easily detect the flickering of the radiation wave source. When the flickering frequency is greater than 24 times per second, it is regarded as a continuous radiation wave source due to the pers...
