Automated classification of healthy and keloidal collagen patterns based on processing of SHG images of human skin
All-optical microspectroscopic and tomographic tools have a great potential for the clinical investigation of human skin and skin diseases. However, automated optical tomography or even microscopy generate...
PublicationsTowards multimodal nonlinear optical tomography – experimental methodology
All-optical microspectroscopic and tomographic tools reveal great potential for clinical dermatologic diganostics, i.e., investigation of human skin and skin diseases. While optical-coherence tomography...
PublicationsSpatial coherence on micrometer scale measured by a nanohole array
For microscopic interference setups like an arrangement for in-line holographic microscopy a partially coherent illumination with volumes of coherence in the micrometer scale is sufficient and helpful....
PublicationsSuspended-core fiber Sagnac combined dual-random mirror Raman fiber laser
In the present work, a multiwavelength fiber laser based in the combination of a double-random mirror and a suspended-core Sagnac interferometer is presented. The double-random mirror acts by itself as...
PublicationsSimultaneous measurement of three parameters using an all-fiber Mach–Zehnder interferometer based on suspended twin-core fibers
We describe an all-fiber Mach–Zehnder interferometric configuration based on a suspended twin-core fiber. Because of the birefringence of the fiber cores, two interferometers are obtained by illuminating...
PublicationsMagnetic fluid hyperthermia: focus on superparamagnetic iron oxide nanoparticles
Due to their unique magnetic properties, excellent biocompatibility as well as multi-purpose biomedical potential (e.g., applications in cancer therapy and general drug delivery), superparamagnetic iron...
PublicationsCrisp and soft multivariate methods visualize individual cell nuclei in Raman images of liver tissue sections
Raman and infrared spectroscopy have been recognized to be promising tools in clinical diagnostics because they provide molecular contrast without external stains. Here, vertex component analysis (VCA)...
PublicationsCrystallization of alpha- and beta-carotene in the foregut of Spodoptera larvae feeding on a toxic food plant
In the animal kingdom, carotenoids are usually absorbed from dietary sources and transported to target tissues. Despite their general importance, the uptake mechanism is still poorly understood. Here we...
PublicationsHigh force measurement sensitivity with fiber Bragg gratings fabricated in uniform-waist fiber tapers
Fiber Bragg gratings (FBGs) inscribed in the waist of tapered photosensitive fibers offer specific attractive properties for sensing applications. A small-diameter fiber reduces structural influences for...
PublicationsOptimized coherence parameters for high-resolution holographic microscopy
A holographic in-line microscope setup with a glass sample carrier commonly uses a coherent laser light source, with the disadvantage of an incomplete suppression of disturbing interferences and coherence...
