The invention discloses a digital light spot scintillation detection system, which comprises a light spot scintiloscope and a software system; the detection system is characterized in that the light spot scintiloscope comprises a shell, an eye patch, a light spot scintillation component, a viewing angle imaging component and a host, wherein the software system is embedded in the host; and the software system comprises an eye movement tracking module, a light spot scintillation parameter control module, a critical flicker fusion frequency measuring and curve drawing module, a database management module, a data statistics and analysis module and a system maintenance module. According to the digital light spot scintillation detection system provided by the invention, intelligent measurement of critical flicker fusion frequency is achieved; through host-controlled measurement and recording and analyzing measurement data and by displaying output via a display screen in real time, individualand group assessment can be facilitated; by tracking pupils of detected personnel via a monitoring camera and the eye movement tracking module and by implementing modes of CFF curve drawing and real-time displaying, the credibility of a detection result is improved; and through optimal design of an overall structure, miniaturization of the equipment is achieved, and carrying and on-site implementation can be facilitated.
Description
technical field [0001] The invention relates to the technical field of critical flash fusion frequency testing, in particular to a digital bright spot flicker detection system. Background technique [0002] When the flicker frequency reaches a certain number of times, due to the effect of the visual afterimage, the human body does not feel the flicker but sees it as continuous light, that is, flicker fusion occurs, and its lowest frequency is called critical flick fusion frequency (CFF). Due to the convenience of CFF detection, low-cost equipment, and relatively stable results, it has been widely used in the assessment of sleep insufficiency and rhythm disorders, cognitive work fatigue, and drug central effects, and has formed a reference standard and consensus—that is, it is 3-3% lower than before the task. 5Hz indicates the work fatigue state. [0003] At present, there are commercially available products of various brands of bright spot scintillation instruments at home ...
