    2. Endoscopic en-face optical coherence tomography and fluorescence imaging using correlation-based probe tracking

      Endoscopic en-face optical coherence tomography and fluorescence imaging using correlation-based probe tracking
      Forward-viewing endoscopic optical coherence tomography (OCT) provides 3D imaging in vivo, and can be combined with widefield fluorescence imaging by use of a double-clad fiber. However, it is technically challenging to build a high-performance miniaturized 2D scanning system with a large field-of-view. In this paper we demonstrate how a 1D scanning probe, which produces cross-sectional OCT images (B-scans) and 1D fluorescence T-scans, can be transformed into a 2D scanning probe ...

    3. A novel 3D printed hollow microneedle microelectromechanical system for controlled, personalized transdermal drug delivery

      A novel 3D printed hollow microneedle microelectromechanical system for controlled, personalized transdermal drug delivery
      The advancement of drug delivery devices is critical for the individualization of patient treatment and the improvement of healthcare. Here, we introduce the 3DMNMEMS, a novel device that combines 3D printing, microneedles (MNs) and Microelectromechanical Systems (MEMS), allowing versatile and controllable by the user transdermal drug delivery. Hollow MNs were designed and 3D printed using Stereolithography, followed by integrating into a MEMS. By employing advanced imaging techniques, we monitored the ...

    4. Computational Methods for Image Acquisition and Analysis with Applications in Optical Coherence Tomography

      Computational Methods for Image Acquisition and Analysis with Applications in Optical Coherence Tomography
      The computational approach to image acquisition and analysis plays an important role in medical imaging and optical coherence tomography (OCT). This thesis is dedicated to the development and evaluation of algorithmic solutions for better image acquisition and analysis with a focus on OCT retinal imaging. For image acquisition, we first developed, implemented, and systematically evaluated a compressive sensing approach for image/signal acquisition for single-pixel camera architectures and an OCT ...

    5. Optimization of X-ray Investigations in Dentistry Using Optical Coherence Tomography

      Optimization of X-ray Investigations in Dentistry Using Optical Coherence Tomography
      The most common imaging technique for dental diagnoses and treatment monitoring is X-ray imaging, which evolved from the first intraoral radiographs to high-quality three-dimensional (3D) Cone Beam Computed Tomography (CBCT). Other imaging techniques have shown potential, such as Optical Coherence Tomography (OCT). We have recently reported on the boundaries of these two types of techniques, regarding. the dental fields where each one is more appropriate or where they should be ...

    6. En‑face optical coherence tomography analysis of gold and silver nanoparticles in endodontic irrigating solutions: An in vitro study

      En‑face optical coherence tomography analysis of gold and silver nanoparticles in endodontic irrigating solutions: An in vitro study
      Optical coherence tomography (OCT) is a non‑invasive, non‑radioactive optical diagnostic method based on low‑coherence interferometry, which achieves images with different orientation. In dentistry, its major advantage is represented by the localization and characterization of the smallest defects in hard dental tissues, dental materials and of the smallest details in dental anatomy (supplementary canals, recesses, isthmuses, or intra‑radicular connections). The aim of the present in vitro study ...

    7. 1st International Conference Advances in 3OM: Opto-Mechatronics, Opto-Mechanics and Optical Metrology, Timisoara, Romania, December 13, 2021

      1st International Conference Advances in 3OM: Opto-Mechatronics, Opto-Mechanics and Optical Metrology, Timisoara, Romania, December 13, 2021
      The 3OM concept reunites three complementary domains: (1) Opto-Mechatronics is a blend of Optics Photonics, Precision Mechanics, Electronics, Control Automation, as well as IT. (2) Opto-Mechanics usually fills the gap between the high requirements of Optical Design and the capabilities of Mechanical technologies, addressing tolerances, errors, positioning issues, and methods to tackle them. Kinematic and dynamic aspects of optical systems with moving parts are also approached, and this leads back ...

    8. Akinetic Swept-Source Master–Slave-Enhanced Optical Coherence Tomography

      Akinetic Swept-Source Master–Slave-Enhanced Optical Coherence Tomography
      This paper presents a different approach for processing the signal from interferometers driven by swept sources that exhibit non-linear tuning during stable time intervals. Such sources are, for example, those commercialised by Insight, which are electrically tunable and akinetic. These Insight sources use a calibration procedure to skip frequencies already included in a spectral sweep, i.e., a process of clearing the spectrum. For the first time, the suitability of ...

      Photonics for Forensics: new publication on peer-reviewed journal
      A study on the applicability of optical coherence tomography imaging for questioned documents examination, particularly identification documents (national ID cards and passports) has just been published by researchers from the Applied Optics group, the Forensic Science Research group in our School, and Foster and Freeman, Ltd., a manufacturer of forensic science lab equipment. This is a unique study for the group and the wider school, where Photonics was so exquisitely ...

      Sub-surface characterisation of latest-generation identification documents using optical coherence tomography
      The identification of individuals, particularly at international border crossings, coupled with the evolving sophistication of identity documents are issues that authorities must contend with. Particularly, the ability to distinguish legitimate from counterfeit documents, with high throughput, sensitivity, and selectivity is an ever-evolving challenge. Over the last decade, an increasing number of security features have been introduced by authorities in identification documents. The latest generation of travel documents (such as passports ...

    11. Dental Diagnosis and Treatment Assessments: Between X-rays Radiography and Optical Coherence Tomography

      Dental Diagnosis and Treatment Assessments: Between X-rays Radiography and Optical Coherence Tomography
      A correct diagnosis in dental medicine is typically provided only after clinical and radiological evaluations. They are also required for treatment assessments. The aim of this study is to establish the boundaries from which a modern, although established, imaging technique, Optical Coherence Tomography (OCT), is more suitable than the common X-ray radiography to assess dental issues and treatments. The most common methods for daily-basis clinical imaging are utilized in this ...

      Apparatus and method for processing the signal in master slave interferometry and apparatus and method for master slave optical coherence tomography with any number of sampled depths
      The present invention related to an apparatus and method for master slave interferometry, referred to as Complex Master Slave (CMS). The method and apparatus can be used to provide complex-valued measurements of a signal reflected from an axial position inside an object or of signals reflected from points at several axial positions inside an object.
