Considering the effect of vibration on imaging quality of photoelectric system,we established a simulated photoelectric imaging test system based on a 6-FOM vibration isolation system and the image capturing system.Image sequences under different vibration environments were collected through the vibration table tests,and the influence of such vibration parameters as amplitude and frequency on imaging quality were analyzed by calculating the sharpness of the images.Results obtained were studied and discussed in detail,which showed that:1) Compared with the frequency,the amplitude was even more influential on imaging quality of the photoelectric system; and 2) The effect of the high-frequency vibration was greater than that of the low-frequency vibration under the condition of equal vibration amplitude of different frequencies.The results of the study is useful for the research on the mechanism of influence of vibration to imaging quality of photoelectric system,and can be taken as a reference for the design of vibration isolation and the rational choice of shock absorber.
