However, when imaging tissue dynamics <i>in vivo</i>, inter-frame displacement introduces decorrelation noise that compromises motion detection performance, particularly in terms of sensitivity and accuracy. Here, we demonstrate that the displacement-related decorrelation noise in FD-OCT can be accurately corrected by restoring the initial sampling points using our proposed Phase-Restoring Subpixel Image Registration (PRESIR) method. Derived from a general FD-OCT model, the PRESIR method enables translational shifting of complex-valued OCT images over arbitrary displacements with subpixel precision, while accurately restoring phase components. Unlike conventional approaches that shift OCT images either in the spatial domain at the pixel level or in the spatial frequency domain for subpixel correction, our method reconstructs OCT images by correcting axial displacement in the spectral domain (k domain) and lateral displacement in the spatial frequency domain. We validated the PRESIR method through simulations, phantom experiments, and <i>in-vivo</i> ORG in both rodents and human subjects.

Compared with the CuI/MgZnO self-powered PD, the optimised heterojunction PD (CuI/Cu<sub>2</sub>O/MgZnO) exhibits significantly improved self-powered properties. Under 325 nm UV light at an intensity of 450 µW/cm<sup>2</sup>, the CuI/Cu<sub>2</sub>O/MgZnO heterojunction PD shows exceptional photoelectric performance, featuring a high photo-to-dark current ratio of 1611, a large responsivity of 48.43 mA/W, and rapid rise and decay times of 261 ms and 890 ms, respectively, without any external power supply. Incorporating the Cu<sub>2</sub>O interface layer results in notable enhancements in responsivity and detectivity compared to the heterojunction without the Cu<sub>2</sub>O layer. This improvement is attributed to heterojunction interface contact, energy band engineering, and the tunneling effect. The Cu<sub>2</sub>O layer expands the depletion zone and promotes charge separation. Due to its thinness, charges can tunnel through the Cu<sub>2</sub>O layer from one metal electrode to another. Furthermore, the interfacial Cu<sub>2</sub>O layer can alter the valence band offset and the conduction band offset of the p-CuI/n-MgZnO junction, enhancing carrier transport between MgZnO and CuI. These results lay the groundwork for using self-powered MgZnO-based heterojunction photodetectors in light-based devices in the future. They also demonstrate the potential of designing novel heterojunctions to create high-performance self-powered PDs for UV detection.</p>","PeriodicalId":722,"journal":{"name":"Optical Review","volume":"5 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143528227","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we reported the optically-pumped mid-infrared laser generation in the mixed Tm<sup>3+</sup>:LuScO<sub>3</sub> sesquioxide crystals.

The method first removed the rigid body displacement between images by registering the lowest point of the macular central fovea, and then analyzed the maximum strain in the direction of retinal thickness in the images by using the digital image correlation (DIC) method. Subsequently, the spatial distribution of the maximum strain of the retina was obtained by linear interpolation in a spatial coordinate system through coordinate system transformation.
