Influence of vibration on transfer function of television imaging system

In order to study the transfer function of television imaging system affectted by vibration,the transfer functions under different vibrations were analyzed and compared, and through utilizing the energy integral method.And then the laws were measured and verificated by the fast mirror system and ISITE measurement system. Simulation and experiments results show that for the TV imaging system developed, when the frequency of vibration is lower than the exposure frequency,the downtrend of the transfer function can increase from 0.167 in static condition to 0.237 with the increasing frequency of vibration ; when the frequency of vibration is higher than the exposure frequency,the downtrend of the transfer function can fluctuate increasingly and gradually tends to 1.42 times that of the static condition.
