Experimental Demonstration of Single-Pixel Imaging Using a Polarization-Maintaining Fiber Array With Four Fibers
Endoscopes with small diameters are widely desired in medical and industrial fields. In this letter, we experimentally demonstrated single-pixel imaging (SPI) using a polarization-maintaining (PM) fiber array with few cores to achieve endoscope size reduction. We designed a PM fiber array with four fibers for the SPI system. The fiber array generated spatial patterns modulated using thermo-optic phase modulation. These patterns were then used to project objects, and the light intensities were detected. Using the pattern information and obtained intensities, we reconstructed the object information. This letter provides the first experimental demonstration of an SPI system incorporating a PM fiber array with four fibers. The results represent an advancement for realizing a compact endoscope based on SPI algorithms. The resolution of the reconstructions obtained using the SPI system can be improved. Thus, the results of this letter can be used as a reference for further developments.
