单像素成像的乘法关联调控仿真与实验

Simulation and Experiment of Single Pixel Imaging Based Correlated Manipulation for Multiplication

摘要: 单像素成像是一种新型的成像方式，仅需一个单像素探测器配合空间光调制器便能对物体成像。已有单像素成像的研究集中在调制方式、重建算法和应用领域等方面，局限于固定不变的掩模与探测值之间的一一对应关系，给单像素成像的功能性拓展造成了阻碍。本文提出了一种基于单像素成像的乘法关联调控，使用探测值与受控掩模重建得到被调控的物体，实现对物体的间接调控，不仅有效地拓展了单像素成像的功能，也为关联调控的发展提供了一种可借鉴的方案。

Abstract: Single pixel imaging (SPI) is a novel imaging method that needs only one pixel accompanied with spatial light modulator to achieve image. Recent years have witnessed the SPI developments in modulation methodologies, reconstruction algorithms and applications. However, the fundamental framework of the SPI inevitably requires a series of pre-set sensing matrixes that obtain the detec-tions on a one-to-one basis, limiting the flexibility of the SPI, hindering the extent of its functionality. In this paper, we propose a SPI-based correlated manipulation that realizes object multiplication via indirectly multiplication of the sensing matrix. Our method implements an indirect manipula-tion over the object, not only effectively extending the SPI functionalities, but also providing a val-uable solution for correlated manipulation with the SPI.
