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.

Modulation transfer function (MTF) is one of significant parameters for designing and evaluating an photoelectric imaging system. As the traditional MTF measurement algorithm cannot meet the need of discrete sampling characteristics for photoelectric system, an automatic interpolaton and sub-pixel matching algorithm based on slit tilting method is proposed.Through the least-square analysis of line spread function (LSF),the tilting angle can be automatically calculated, and interpolaton of sub-pixel data can be precisely reconstructed. The noise of oscillation can be effectively restrained by a hanning window function. A device composed of target generator system, off-axis reflective collimator, mechanical adjustment, electrical control system, video acquisition module and comprehensive software was setup. The validity of the method was verified by experiments. The repeatability reached 0.007。
