Fabrication of Surface Relief Micro‐Gratings in Azobenzene Films and Their Conversion to Gold Microwires

open access: yesMicro &Nano Letters, Volume 21, Issue 1, January/December 2026.
A maskless prism‐based laser interference lithography technique is presented for fabricating large‐area surface‐relief micro‐gratings in azobenzene thin films, achieving a record grating pitch of ∼64.5 m. The micro‐gratings are subsequently converted into periodic gold microwire arrays via selective dissolution and lift‐off, enabling scalable micro ...

Practical eight-frame algorithms for fringe projection profilometry

open access: yesOptics Express, 2013
In this paper we present several eight-frame algorithms for their use in phase shifting profilometry and their application for the analysis of semi-fossilized materials. All algorithms are obtained from a set of two-frame algorithms and designed to compensate common errors such as phase shift detuning and bias errors.

Displacement and Vibration Measurements with Interferometers: Benchmark Configurations, Performance, and R&D Opportunities

open access: yesAdvanced Photonics Research, Volume 6, Issue 12, December 2025.
Self‐mixing interferometry is a powerful technique that brings together the exceptional sensitivity of phase measurements with the unequalled simplicity of the self‐mix configuration based on modulation of the cavity field induced by the return from the target. According to the selected measurand, displacement or vibration, and to the analog of digital

Sulfonated PEDOT‐Modified Decellularized Arteries as Electroactive Scaffolds for Vascular Tissue Engineering

open access: yesJournal of Biomedical Materials Research Part A, Volume 113, Issue 12, December 2025.
ABSTRACT Electroactive biomaterials present new opportunities for “smart” vascular grafts capable of supporting tissue integration while enabling electrical stimulation, sensing, or real‐time modulation of the vascular environment. In this study, a conductive vascular conduit was engineered by incorporating sulfonated poly(3,4‐ethylenedioxythiophene ...

Three‐dimensional phenotyping of soybean roots under different water treatment conditions using fringe projection

open access: yesThe Plant Phenome Journal, Volume 8, Issue 1, December 2025.
Abstract Accurate phenotyping of root traits is essential for understanding how plants respond to varying soil water treatment conditions, yet traditional phenotyping methods are often destructive and limited in capturing the full three‐dimensional (3D) complexity of root systems.

Study on 3D shape and deformation measurement of a radiator fan based on high-speed binary defocused fringe projection

open access: yesMechanical Engineering Journal, 2016
The binary defocused fringe can overcome the nonlinear effect of an ordinary commercial digital projector and generate a good sinusoidal light field. In this paper, the binary fringe encoding method was chosen to complete the high-speed fringe projection

Automated Covalent Microcontact Bioprinting of Lubricant‐Infused Microarrays for Biological Assays

open access: yesSmall, Volume 21, Issue 49, December 10, 2025.
The microcontact bioprinting protocol, through industrial risk assessment and optimization, has allowed to achieve scalability and automation of lubricant‐infused microarray fabrication. Additionally, bacteriophage microarrays created with this protocol showed preserved lytic activity and self‐propagation ability after bioprinting through an 2,3‐bis‐(2‐
