The inherent sensitivity to perturbations for the multimode fiber (MMF) has become a major obstacle single MMF-based imaging advancing towards applications. MMF-enabled compressive provides fundamental and elegant solution by employing short MMF as speckle illuminator inherently stable single-mode remaining flexible part. However, existing schemes hardly achieve high resolution, transmittance, minimization robustness at same time. Here, we propose random-phased plate quickly scramble...
Two-photon endomicroscopy (2PEM), an endomicroscopic imaging technique based on the two-photon excitation effect, provides several technical benefits, including high spatiotemporal resolution, label-free structural and metabolic imaging, optical sectioning. These characteristics make it extremely promising for biomedical applications. This paper classifies distal-scanning 2PEMs their actuation mechanism (PZT or MEMS) excitation–collection path configuration (common separate path). Recent...
Photon-based entanglement sources, crucial for obtaining entangled states, are typically generated via spontaneous parametric down-conversion. However, birefringence in nonlinear crystals causes spatial or temporal walk-off, reducing photon quality. The theoretical analysis attributes birefringent walk-off to dispersive materials curbed by pre- and post-compensation. We experimentally validate this method, enhancing polarization-entangled measured the Bell state along with a violation of...
Nowadays, with the continuous development of optical quantum sensor technology, importance entanglement source is increasing day by day. As an indispensable part systems, has a wide prospect application in communication, imaging, computing, life science and so on. However, current power consumption preparation cost sources are relatively huge, which impedes further integration expansion. In view these problems, we establish model pumped low-power laser diode based on spontaneous parametric...
With the continuous development of optical quantum sensor technology, importance entanglement sources is growing. As an essential component systems, have broad applications in communication, imaging, computing, and other fields. However, high-power consumption preparation costs associated with these hinder their integration expansion. To address issues, we conducted experiments using a 40mW laser diode typical type-II barium metaborate (BBO) crystal to prepare low-power low-cost source. Our...
