Abstract
Modulation transfer function (MTF) is one of significant parameters for designing and evaluationg an photoelectric imaging system.As the traditional MTF measurement algorithm cannot meet the need of dynamic measurement for photoelectric system. A device composed of composed of three parts, including dynamic target generation unit, carrier motion simulation unit, data processing and control unit was setup. It is found that when the platform vibrates at low frequency, the decreasing speed of the dynamic transfer function of the television imaging system increases with the increase of the vibration frequency. When the platform vibrates at high frequency, the decreasing velocity of the dynamic transfer function of the television imaging system changes very weakly with the increase of the vibration frequency of the platform. When the platform vibrates at high frequency, the fluctuation of the decreasing velocity of the dynamic transfer function of the television imaging system decreases continuously with the increase of the vibration frequency, and gradually approaches 1 when the platform is at rest1.42 times.
