Electrical measurement of sediment layer thickness under suspension flows

This paper reports a new technique to measure the thickness of a layer of deposited sediment as a function of time, independent of the flow conditions or presence of suspended sediment above the layer. Small electrodes on the bottom and a reference electrode in the fluid above were used to measure the resistance of the layer with a small AC current and a bridge circuit. Using a multiplexer and ...

Measurement of Meniscal Surface Layer Thickness Using Optical Coherence Tomography

Introduction: With increasing focus on the detection, study and treatment of early stage osteoarthritis (OA), there is increasing interest in novel imaging modalities capable of detecting changes in various joint tissues during early stages of the disease. The surface of the meniscus consists of a relatively thin layer of randomly orientated collagen fibers that overlays the circumferential col...

optical coherence tomographic measurement of peripapillary retinal nerve fiber layer thickness in normal human eyes

purpose: to measure peripapillary retinal nerve fiber layer (rnfl) thickness in normal human eyes by optical coherence tomography (oct). methods: eighty-one eyes of 45 normal participants were studied. each person underwent a complete ophthalmic examinations, including measurement of visual aquity and intraocular pressure and evaluation of the anterior segment, optic disc, and retinal nerve fib...

Measurement of the thickness of an insensitive surface layer of a PIN photodiode

We measured the thickness of an insensitive surface layer of a PIN photodiode, Hamamatsu S3590-06, used in the Tokyo Axion Helioscope. We made alpha-particles impinge on the PIN photodiode in various incidence angles and measured the pulse height to estimate the thickness of the insensitive surface layer. This measurement showed its thickness was 0.31±0.02 μm on the assumption that the insensit...
