Optical Viscometry of Spinning Sol Coatings
Optical interferometric monitoring of spin coating (optospinography) has allowed close observation of the temporal evolution of a thin silicate sol film (typically at 2000 rpm, 100 Hz data acquisition). The kinematic viscosity data obtained, using a simple analytical model, are validated with those from a mineral oil standard, with agreement well within the experimental uncertainties. For spin ...
متن کاملExperimental Visualization of Labyrinthine Structure with Optical Coherence Tomography
Introduction:Visualization of inner ear structures is a valuable strategy for researchers and clinicians working on hearing pathologies. Optical coherence tomography (OCT) is a high-resolution imaging technology which may be used for the visualization of tissues. In this experimental study we aimed to evaluate inner ear anatomy in well-prepared human labyrinthine bones.Materials and Methods:Thr...
متن کاملClinical Applications of Optical Coherence Tomography in Ophthalmology
Assessment of the peripapillary nerve fiber layer and macular thickness can be determined in ophthalmology using optical coherence tomography (OCT). Decreased nerve fiber layer thickness and macular ganglion cell thickness in optic nerve ischemia have been correlated with visual field loss. OCT allows deep optic nerve head evaluation which helps understand pathophysiology of diseases. Furtherm...
متن کاملHigh Shear Rate Viscometry
We investigate the use of two distinct and complementary approaches to measuring the viscometric properties of low viscosity complex fluids at high shear rates up to 80,000 s−1. Firstly we adapt commercial controlled-stress and controlled-rate rheometers to access elevated shear rates by using parallel plate fixtures with very small gap settings (down to 30 μm). The resulting apparent viscositi...
متن کاملOptical Coherence Tomography Angiography
Optical coherence tomography angiography (OCTA) is a noninvasive approach that can visualize blood vessels down to the capillary level. With the advent of high-speed OCT and efficient algorithms, practical OCTA of ocular circulation is now available to ophthalmologists. Clinical investigations that used OCTA have increased exponentially in the past few years. This review will cover the history ...
