Surgeon-friendly 3D Navigation: Bridging the Gap between Conventional Medical Imaging and Holographic Technology

Hepatopancreato-biliary (HPB) surgeons, when planning complex cases of pancreatic cancer, lose precious time because of difficulties in visualising the interaction between tumour and blood vessels and identifying patient-specific anatomy. To tackle this issue, the Integrated Imaging Workstation (IIW) was prototyped by e/MTIC and Philips. This...

Large volume holographic imaging for biological sample analysis

Significance: Particle field holography is a versatile technique to determine the size and distribution of moving or stationary particles in air or in a liquid without significant disturbance of the sample volume. Although this technique is applied in biological sample analysis, it is limited to small sample volumes, thus increasing the number...

Roadmap on digital holography-based quantitative phase imaging

Quantitative Phase Imaging (QPI) provides unique means for the imaging of biological or technical microstructures, merging beneficial features identified with microscopy, interferometry, holography, and numerical computations. This roadmap article reviews several digital holography-based QPI approaches developed by prominent research groups....

Towards a single shot holographic diagnosis of Schistosomiasis haematobium

Large scale, highly sensitive and specific diagnostic tools are needed to eliminate the transmission of schistosomiasis. This report expands upon the novel approach from M. Hoeboer and P.M. Nijman. Their Smart Optical Diagnostic Of Schistosomiasis device (SODOS), combining the principles of flow cytometry and digital holography, was able to...

Explorative study towards the integration and combination of three technologies into a virtual control system

Interacting with holograms is something which is widely speculated about. Combining holographic projections with haptic feedback and gesture control might bring this concept closer to reality. This project aims at exploring the possibilities of combining these three technologies into a combined virtual control system. Project owner Safran...

From Floor Plans to Condominium Rights Through an Augmented Reality Approach

The creation of a 3D cadaster faces a number of different challenges. Two of them are the collection of data on already existing 3D structures and the visualization for non-experts. The paper uses Augmented Reality (AR) technology for the visualization of models created from plans required in Austria to create condominiums. The advantages of...

Digital holographic particle image velocimetry

This thesis contributes to the development of an instrument that can measure fluid flow velocity in a three-dimensional (3D) measurement domain by holographic imaging.

Characterization of the diffraction efficiency of polymer-liquid-crystal-polymer-slices gratings at all incidence angles

Recently, a novel holographic diffraction grating made of polymer slices alternated to homogeneous films of nematic liquid crystal (POLICRYPS) was realized. We study the optical performance of the POLICRYPS gratings by both numerical simulations and experiments. Characterization of the grating at normal and conical reading mount are performed....

Digital holographic particle image velocimetry: Eliminating a sign-ambiguity error and a bias error from the measured particle field displacement

Holographic particle image velocimetry using Bacteriorhodopsin

To gain better insight into the behaviour of turbulent flow there is a demand for a practical measurement instrument to perform three-dimensional flow measurements. Holography is a three-dimensional imaging technique, and as such is ideally suited for this purpose. Because flow media (such as water and air) are generally transparent, optical...

Optimizing Fourier filtering for digital holographic particle image velocimetry

Reusable holographic velocimetry system based on polarization multiplexing in Bacteriorhodopsin

We present a novel holographic particle image velocimetry (HPIV) system using a reversible holographic material as the recording medium. In HPIV the three-dimensional flow field throughout a volume is detected by adding small tracer particles to a normally transparent medium. By recording the particle distribution twice with a known time shift...
