Multilayer thin films were deposited onto indium tin oxide (ITO)-coated glass substrates using the spin-coating technique, which facilitated phase separation, resulting in the final device configuration: ITO/PEDOT: PSS/PVK: GNs/Alq3/Al. The optical properties of the active materials were characterized through absorption and photoluminescence (PL) spectroscopy. The GNs exhibited an optical bandgap of approximately 2.3 eV, with absorption and emission spectra revealing the presence of deep sublevels and surface states. The electrical characteristics of the hybrid device were evaluated by analyzing current-voltage (I-V) measurements, which demonstrated distinct transport regimes: a linear ohmic region at low voltages, an exponential trap-filled limited region, and a power-law dependence at higher voltages. Electroluminescence (EL) spectra were recorded at forward bias voltages of 10, 15, and 20 V at room temperature, showing a broad emission spanning from 350 to 700 nm. The emission color was analyzed using the CIE 1931 color space, with correlated color temperature (CCT) values calculated for different operating voltages. The observed optical and electrical behavior is attributed to radiative transitions involving deep sublevels (σ–σ, π–π, and n–π*) and surface states within the energy bandgap of the GNs. The results demonstrate the potential of integrating graphene nanoparticles into organic multilayer structures for achieving broad-spectrum electroluminescence.</p></div>","PeriodicalId":722,"journal":{"name":"Optical Review","volume":"33 4","pages":"615 - 622"},"PeriodicalIF":1.0,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148884031","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}

However, the vulnerability of such systems to training-stage data poisoning attacks has not been sufficiently investigated. In this study, we examine how the optical configuration affects poisoning vulnerability in deep-learning-based scattering imaging. Two representative optical configurations, a conventional imaging configuration and a lensless configuration, were compared experimentally. Trigger patterns were embedded in a subset of the training images and paired with attacker-defined target images to induce backdoor behavior. The results showed that the imaging configuration was vulnerable to poisoning attacks, whereas the lensless configuration exhibited substantially lower attack success rates under the same experimental conditions. This difference is likely related to the spatial distribution of speckle information. In the imaging configuration, trigger-related features remained relatively localized, making them easier for the neural network to associate with incorrect reconstructions. In contrast, in the lensless configuration, object and trigger information were more broadly mixed over the sensor plane, which made trigger learning more difficult. These results show that the spatial distribution of optical information affects poisoning vulnerability in scattering imaging systems.</p></div>","PeriodicalId":722,"journal":{"name":"Optical Review","volume":"33 4","pages":"565 - 574"},"PeriodicalIF":1.0,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10043-026-01068-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148884032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By combining a layered transmissive display with a directional backlight, the proposed system enables glasses-free three-dimensional presentation while mitigating the vergence–accommodation conflict inherent in conventional binocular stereoscopic displays. Binocular disparity is presented by forming discrete viewing zones using a directional backlight, while multiple focal planes are generated by stacking display layers along the depth direction. In addition, we introduce a directional backlight based on a retroreflective configuration together with a return-path-only modulation scheme using vertical-alignment liquid-crystal panels. This approach enables spatially selective light delivery to the intended viewpoints and suppresses unintended double modulation caused by the retroreflective light path, thereby helping to preserve image quality in a layered display configuration. A prototype system was constructed to validate the proposed concept. Experimental observations confirmed that correct left- and right-eye images are observed at the intended viewpoints and that images are selectively formed at focal planes corresponding to the physical depths of the display layers. These results demonstrate the feasibility of a multiplane naked-eye binocular stereoscopic display based on the proposed architecture. The practical limitations of the system, including viewing area, field of view, optical efficiency, and the number of display layers, are discussed, indicating that a moderate number of focal planes provides a reasonable balance between visual comfort and system complexity.</p></div>","PeriodicalId":722,"journal":{"name":"Optical Review","volume":"33 4","pages":"591 - 601"},"PeriodicalIF":1.0,"publicationDate":"2026-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10043-026-01077-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148728782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
