We have demonstrated all-fiber reflective single-pixel imaging with a long working distance and large field of view. By using wavelength-dependent multimode fiber speckle to illuminate the object, the system is made compact and stable. With collimated MMF speckle patterns and an optical fiber receiving device, we achieved reflective optical fiber single-pixel imaging with a working distance of over 5 mm and a field of view of about 9 mm2. By employing compressed sensing, object images can be reconstructed with a sampling rate of about 4%. This work provides a method and reference for practical applications of optical fiber endoscopic imaging with requirements for a long working distance and large field of view.
We demonstrate all-fiber reflective single-pixel imaging with a long working distance and large field of view. The wavelength-dependent multimode fiber speckle is generated to illuminate the object, which further ensures the compactness and stability of the system. By the collimated MMF speckle patterns and the optical fiber receiving device, we achieve reflective optical fiber single-pixel imaging with a working distance of over 5 mm and a field of view of about 9 mm2. Based on compressed sensing, we can reconstruct object images with a sampling rate of about 4 %. This work provides a method and reference for the practical applications of optical fiber endoscopic imaging with requirements for a long working distance and large field of view.
