By the discussion of the impact to system MTF by each link in image chains based on the camera imaging model, the enhancement effect of filter quality factor, the impact to Signal to Noise Ratio (SNR), simulation results of the impact of quality factor on multiple pixels were analyzed. The analysis show that the appropriate filter quality factor could enhance the system MTF after the optical design is done and the sensor is confirmed. If the optimum quality factor setting value of the filter is 1, the system MTF at the Nyquist spatial frequency can be increased by 32%. The test results show that MTF enhancement filter can improve the system imaging performance when the quality factor is 1, and the noise suppression capability is comparable to that of the maximally flat filter in passband. © 2018, Science Press.
