摘　　要：鬼成像是一种新兴的非局域成像技术。由于它具有较高的抗噪声能力以及超高分辨率,使其成为学者们研究的热点问题。鬼成像的优越性使其应用前景非常广泛,而其成像质量是决定鬼成像实用化的重要因素之一。在鬼成像系统中,光电探测器作为核心器件是影响鬼成像的成像质量的重要因素。利用数值模拟,验证了探测器的响应特性对鬼成像的成像质量的影响,并通过均方误差等评价指标来衡量鬼成像的成像质量。发现在计算鬼成像系统中,即使当光电探测器处于非线性响应区域时,相较于直接成像仍然能够较好地恢复出物体的信息,并且此时的抗噪声能力也相对较好。Ghost imaging is a new non-local imaging technology.Because of its high anti-noise ability and ultra-high resolution,i t has become a hot topic of research.The advantages of ghost imaging make its application prospect very wide,and its imaging quality is one of the important factors to determine the practicality of ghost imaging.In the ghost imaging system,photodetector as the core device is an important factor affecting the image quality of ghost imaging.The effect of the detector response characteristics on the image quality of ghost imaging is verified by numerical simulation,and the image quality of ghost imaging is measured by mean square error and other evaluation indexes.This paper finds that in the computational ghost imaging system,even when the photodetector is in the nonlinear response region,it can still recover the information of the object better than the direct imaging,and the anti-noise ability is relatively good at this time.
