Hessian-IDT iteratively reconstructs the scattering potential of the sample using the 3D extension of the Fourier Ptychographic Microscopy (FPM) algorithm, and Hessian regularization and non-negative constraints are added to the iterative process using the Split Bregman algorithm by incorporating prior knowledge about sample smoothness and positivity. Cell simulation and complex sample simulation demonstrate that Hessian-IDT yields higher-quality 3D RI reconstructions compared to existing IDT methods.

Traditional automatic HDR methods are limited by the nonlinear relationship between projector radiance and current, solely relying on exposure time adjustment, which restricts the achievable dynamic range. Moreover, the traditional approach of selecting the brightest unsaturated phase has proven insufficient for improving measurement accuracy. This paper presents a dual-parameter linear imaging model to address these limitations. The proposed model introduces a reference current and implements a current ratio factor, enabling linear control of both exposure time and projector radiance. This approach overcomes the limitations of single-parameter exposure adjustments and nonlinear radiation response, thereby substantially expanding the dynamic range of the FPP system. We propose an automatic method for computing optimal exposure sequences that eliminates the need for surface reflectance calculations, thus enhancing computational efficiency.

This is especially true when using relatively large, spatially extended point sources (≥ 5 µm) or very short working distances (< 10 mm). In such cases, the recorded holograms typically show useful detail only in a small, brightly illuminated central region. Since these conditions are common in practical applications, numerical preprocessing becomes essential. It can substantially improve the quality of the reconstructed wave-fields. This work proposes a hardware-free, single-frame preprocessing method called Logarithmic Dynamic Range (<em>LogDR</em>). It redistributes the recorded irradiance onto a logarithmic scale and then applies local tone mapping. This approach flattens the characteristic Gaussian illumination envelope in DLHM without introducing artifacts. Initial validation with eight illumination-limited holograms of a USAF-1951 target shows that the proposed <em>LogDR</em> method increases the effective field of view by about 13 % and improves the smallest resolvable feature from 3.10 µm to 1.95 µm while reducing background phase noise by four-fold. Compared with other methods, <em>LogDR</em> delivers the best trade-off between field of view, lateral resolution and phase contrast. A biological demonstration on a buccal-mucus smear further reveals peripheral protein aggregates and sub-cellular details that remain hidden in conventional reconstructions. Because <em>LogDR</em> operates without additional exposures, optics or machine-learning models, it offers an immediately deployable enhancement for portable or point-of-care DLHM systems, enabling wider contextual imaging and finer structural analysis under compromised illumination conditions.</div></div>","PeriodicalId":49719,"journal":{"name":"Optics and Lasers in Engineering","volume":"195 ","pages":"Article 109292"},"PeriodicalIF":3.7,"publicationDate":"2025-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144889525","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This approach enables one-step selection of glass combinations tailored to different housing materials. A novel Athermal Glass Map is constructed to unify the system’s thermal defocus, chromatic aberration, and spherical aberration responses into a single coordinate space.
