As a lensless phase retrieval method, extended ptychographic iterative engine (ePIE) has obvious advantages such as high reconstruction accuracy, simple optical path and operation, and shows great application potential in the above field. However, our research results in this work show that current ePIE algorithm cannot measure the phase of illumination probe when it contains a tip-tilt phase. Accurately measuring tip-tilt phase is a foundation and is highly valuable for phase measurement by this algorithm; otherwise, it will result in the failures of all phase measurements. An optimized ePIE algorithm was presented to measure the tip-tilt phase of the probe by optimizing the initial estimate of the tip-tilt phase and limiting the range of reconstructed probe. Its validity was demonstrated by both simulated and experimental results. As examples: in single probe experiments, the relative errors (REs) of the measured phases are 2.06% and 2.40% for the introduced real tilted angles of 0.4991° and 0.9983°, respectively; in a simultaneous double probe experiment, the REs are 1.84% and 1.61% for the above real angles, respectively. The impacts of the initial estimate and the range limitation on measurement result, and noise robustness, were analyzed by simulations. It can measure the tip-tilt phases of multiple probes simultaneously, and also measure the relative piston phase, providing a potential co-focus and co-phase detection method for segmented mirror telescopes, especially for sparse aperture telescopes.</div></div>","PeriodicalId":19511,"journal":{"name":"Optics and Laser Technology","volume":"192 ","pages":"Article 113622"},"PeriodicalIF":4.6,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144670308","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Over the past decade, their discovery has spurred extensive research into electronic systems and other Bloch-wave systems, such as photonic and phononic crystals. However, current studies typically focus on type-II DPs along high-symmetry directions in the first Brillouin zone (FBZ) under mirror symmetry conditions, which are highly restrictive and limit further investigations and applications. To overcome the stringent constraint, here we identify and demonstrate the emergence of type-II DPs at general positions inside the FBZ without requiring the mirror symmetry. The type-II DPs, being accidental degeneracies, are experimentally realized on a metacrystal slab with H-shaped metallic patterns. Our findings indicate that even in the absence of mirror symmetry, type-II DPs can emerge at designated locations inside the FBZ by simply rotating the H-shaped patterns and adjusting geometrical and physical parameters. Furthermore, based on the rotated type-II DPs, off-axis conical diffractions have been realized and experimentally observed. Meanwhile, we discovered that during the rotation process, the type-II DPs transform into off-axis type-I DPs, but still strongly tilted, resulting in the emergence of negative refractions. Hence, the generic method we propose for inducing type-II or strongly tilted type-I DPs without the high-symmetry limitations opens potential avenues for related research. For example, the observed off-axis conical diffraction and negative refraction could inspire future development and applications in photonics and other Bloch-wave systems.</div></div>","PeriodicalId":19511,"journal":{"name":"Optics and Laser Technology","volume":"192 ","pages":"Article 113626"},"PeriodicalIF":4.6,"publicationDate":"2025-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144666015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Most publicly available datasets are synthesized and manually annotated, which is labor-intensive. Consequently, the number of images in these datasets is limited, and they fail to adequately cover the wide range of scene variations. To overcome these challenges, we propose ISTDiffuser, a novel single-frame infrared small target (SIRST) image generation method based on conditional diffusion and contrastive learning. This is the first time a diffusion model has been applied to SIRST image generation tasks, making this work pioneering in the field. In our approach, we introduce a scene-target interaction generation module that ensures the seamless integration of targets into their backgrounds, enhancing the realism and diversity of the synthetic data. Additionally, to better generate images consistent with the style of the instance images, we propose a style-type contrastive learning module. This module employs contrastive loss to guide the diffusion model, enhancing the realism and coherence of the generated images. Experimental results indicate that ISTDiffuser exhibits outstanding image generation capabilities. Furthermore, the generated images show high quality and stability in detection tasks, offering a promising solution to data scarcity in practice.
