| Abstract: | The pupil dynamic characters is an objective physiological parameter, which can not be influenced by subjective motive of people. According to the special requirements of the pupil dynantic image acquisition in objective fatigue test, we have developed a pupil image dynamic acquisition system under the visible light stimulation. This paper mainly introduces the composition and design of the system and emphatically introduces the design principle of light stimulator, the modules and the specific design methods. Experiments show that the system can be effeetively used in the pupil dynamic image acquisition and lay a foundation to find the characteristic parameters of characterizing fatigue. |
