The present invention relates to the field of imaging systems, and in particular to an imaging system with a high static modulation transfer function, comprising an optical system, an imaging controller and a detector. For an area array detector, the static modulation transfer function of the area array detector is improved by reducing the filling rate. For a back-illuminated detector, sub-pixel-level shading is performed on some pixels of the back-illuminated detector to reduce the filling rate. The time delay integration in the digital domain is used to improve the light energy and signal-to-noise ratio of the area array detector or the back-illuminated detector, so that the dynamic modulation transfer function of the output image can be further improved while ensuring that the original signal-to-noise ratio remains unchanged or higher. For a time delay integration detector, the static modulation transfer function of the charge transfer direction of the time delay integration detector is improved by reducing the filling rate in the charge transfer direction, and the light energy loss is compensated by improving the integration order of the time delay integration detector, so as to solve the problem that the dynamic modulation transfer function is relatively low relative to the vertical charge direction.
