人们对编码孔径成像系统的各种应用越来越感兴趣。利用基于互信息的分析框架,我们在简单但有意义的传播和传感器模型下,研究了这种系统的基本极限--以及相关的最佳孔径编码。结果表明,当热噪声占主导地位时,透射率为50%的光谱平坦掩模是最佳的,但当散粒噪声占主导地位时,透射率较低的随机生成掩模性能较好。我们还提供了与经典针孔相机的比较。

英文摘要:
There is growing interest in the use of coded aperture imaging systems for a variety of applications. Using an analysis framework based on mutual information, we examine the fundamental limits of such systems---and the associated optimum aperture coding---under simple but meaningful propagation and sensor models. Among other results, we show that when thermal noise dominates, spectrally-flat masks, which have 50% transmissivity, are optimal, but that when shot noise dominates, randomly generated masks with lower transmissivity offer greater performance. We also provide comparisons to classical pinhole cameras.
