Abstract

Ghost images, as a form of stray light, are caused by the even reflection of residual reflected light between the optical surfaces of the system. Ghost images can seriously reduce imaging clarity, annihilate targets, and seriously affect the performance of optical systems. The Modulation Transfer Function (MTF) is a parameter used for evaluating the imaging quality of optical systems, but traditional MTF cannot reflect the impact of ghost images on the imaging quality of optical systems. In order to investigate the impact of ghost images on the performance of imaging systems, a calculation model for modulation transfer function (MTF) under the influence of ghost images generated by secondary reflections was constructed, and an example verification was conducted on a system. The verification results showed the effectiveness of the calculation model.
