To overcome these challenges, this work proposes a novel Deformable Triple Attention Graph Convolutional Network with Dollmaker Optimization Algorithm (DTAGCN-DOA) for robust mode classification and high-resolution recognition of fractional Bessel-Gaussian (BG) beam-encoded data. Fractional BG beams are generated using a He–Ne laser modulated via a Spatial Light Modulator (SLM), encoding 8-bit digital symbols into structured spatial modes. A total of 51,200 beam intensity images, each corresponding to unique combinations of radial wave number and fractional orbital angular momentum, are collected and preprocessed using Masked Joint Bilateral Filtering (MJBF) to suppress noise while preserving fine spatial features. Feature extraction is conducted via a Boundary-Enhanced Patch-Merging Transformer (BEPMT), combining global semantics and boundary details. The proposed DTAGCN-DOA framework classifies fractional spatial modes using deformable graph convolutions and triple attention mechanisms, with hyperparameters optimized via the DOA. Grayscale images are encoded into 15,000 spatial modes, transmitted optically, and decoded using the trained model. It achieves 99.88 % accuracy, 31.4 dB PSNR, and 0.995 confidence, ensuring reliable, high-fidelity FSO data recognition.</div></div>","PeriodicalId":19586,"journal":{"name":"Optics Communications","volume":"596 ","pages":"Article 132428"},"PeriodicalIF":2.5,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145159253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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, due to depth-variant and wavelength-variant imaging performance, traditional optical designs struggle to cover the entire depth range of interest, where severe bandwidth limit exists. Here, we propose a method of learning virtual lenses (VLs) to beat the optical limits of the singlet lens, and construct a hybrid real-virtual system to obtain broadband AEDOF images. By positioning object imaging depths, the multiple VLs are adaptively embedded in parallel and conjugated with the singlet lens to compensate for imaging differences of these depths. Sequential depth-dependent achromatic images are produced by VLs and fused to recover high-quality image. Comparing to the input image, our method demonstrates an average improvement of 12.3907 dB in Peak Signal-to-Noise Ratio (PSNR), and 0.2437 in Structural Similarity Index Measure (SSIM). Learning-based VLs can dynamically compensate for the real lens, overcoming the bandwidth limits of traditional optics and successfully realizing ultracompact AEDOF imaging. The proposed method provides a feasible solution for configurable computational imaging, allowing for the creation of accurate mapping between high-fidelity images and a single large aperture meta-optic.
