In this letter, sensitivity analysis is adopted to interpret why correspondence ghost imaging can restore better images with fewer reference patterns which have larger bucket value fluctuation: these selected patterns are more alike with regard to the target to be restored. The contribution of reference patterns to imaging can be quantified as sensitivity coefficients. In addition, the peak signal-to-noise ratio and mean square error are calculated to compare the restored image quality, and results confirmed that sensitivity coefficients are more robust than bucket value fluctuation in the presence of noise for selecting reference patterns.

对应重影成像的灵敏度分析

在这封信中,采用灵敏度分析来解释为什么对应重影成像可以使用较少的参考模式(桶值波动较大)恢复更好的图像:这些选择的模式对于要恢复的目标更相似。参考图案对成像的贡献可以量化为灵敏度系数。此外,计算峰值信噪比和均方误差以比较恢复的图像质量,结果证实,在存在噪声的情况下,用于选择参考图案的灵敏度系数比桶值波动更鲁棒。
