摘要:

我们分析了无透镜压缩成像(LCI)架构中的信噪比(SNR)。该结构由单个检测元件的传感器和可编程元件阵列的孔径组件组成。LCI可以与压缩感测结合使用,以压缩测量的压缩形式捕获图像。在本文中,我们进行信噪比分析的LCI和比较它与成像的针孔或镜头。我们将表明,在LCI的SNR是独立的图像分辨率,而在针孔孔径成像或透镜孔径成像的SNR随着图像分辨率的增加而降低。因此,如果图像分辨率足够大,则LCI中的SNR高得多。

英文摘要:

We analyze the signal to noise ratio (SNR) in a lensless compressive imaging (LCI) architecture. The architecture consists of a sensor of a single detecting element and an aperture assembly of an array of programmable elements. LCI can be used in conjunction with compressive sensing to capture images in a compressed form of compressive measurements. In this paper, we perform SNR analysis of the LCI and compare it with imaging with a pinhole or a lens. We will show that the SNR in the LCI is independent of the image resolution, while the SNR in either pinhole aperture imaging or lens aperture imaging decreases as the image resolution increases. Consequently, the SNR in the LCI is much higher if the image resolution is large enough.
