| Résumé: | In this study, the rebound vibration characteristics of the internal mirror of an SLR camera are investigated using experimental models. The mechanism of the mirror rebound phenomena is tested by using four types of rectangular metal plate models. The mirror (plates) model is supported by fixing its longitudinal edge on a horizontal rotatable shaft. The mirror plate swings down freely around a horizontal axis and hits a stopper. A laser displacement meter is used to measures the amount of rebound and the mirror model vibration behavior. It is clear that the contact time with the stopper is determined by the first mode of vibration in contact with the stopper. The higher mode effects to the rebound angle. The rebound angle depends on the mode of the mirror model. The predictions for the rebound angle agreed qualitatively well with the experimental results. |
