Single-Pixel Imaging Based on Optical Fibers

Abstract

In single-pixel imaging (SPI) systems, the traditional free-space photodetector can be easily interfered. Its size and configuration limit its applications in complex and restricted scenarios. In this study, we develop an SPI based on optical fibers. We use a single inclined face optical fiber as an SPI detection device to realize multidimensional remote imaging in slim channels. This system is immune to interference from external ambient lights, and it is flexible to be moved and rotated to implement endoscopic observation inside various narrow spaces, such as fluid tubes and electronic device gaps. Furthermore, it can be used in medical endoscopic imaging and medical intervention therapy.
