    摘要： Provided is a method for measuring fluid's viscosity and mass flow, including the steps of immersing one end of an optical fiber into fluid, emitting a light beam by a light source, receiving the light beam by the optical fiber; and measuring the viscosity and the mass flow of the fluid in a sink based on a displacement of the one end of the optical fiber. The method further includes tapering the one end of the optical fiber and coating a surface of the one end of the optical fiber with a deposited gold thin film as a mirror. The light source is an unpolarized diode laser. Accordingly, the size of the measurement system setup is reduced by using ultra-small sensors. Moreover, the present disclosure also provides methods for fluid's viscosity and mass flow measurement by using intensity modulating sensors, elliptical core two-mode fiber-optic sensors and Fabry-Perot interferometer sensors.

    摘要： Portable coagulation monitoring devices, systems, and methods are disclosed. Namely, a test cartridge is provided for use in a portable coagulation monitor (PCM) device. Further, the test cartridge comprises two glass-filled thermoplastic polymer plates and a disposable blood introduction device. The two glass-filled thermoplastic polymer plates are arranged substantially in parallel with a small gap therebetween for receiving a sample of blood to be tested. Using the PCM device, the two glass-filled thermoplastic polymer plates can be moved linearly relative to each other. Methods of measuring coagulation response in a blood sample using the test cartridge and the PCM device are provided. A method of introducing blood into the test cartridge using the disposable blood introduction device is provided.

    摘要： A fluid characterization measuring instrument is disclosed that comprises a sample vessel for a bulk complex sample fluid having a capacity that is substantially larger than a domain size of the complex sample fluid and that is sufficiently large to cause bulk scattering effects to substantially exceed surface effects for the complex fluid sample, a coherent light source positioned to illuminate the bulk complex sample fluid in the sample vessel and a first fibre having a first end positioned to receive backscattered light from the sample after it has interacted with the sample. The first fibre can also be positioned close enough to an optical axis of the coherent light source and to the sample vessel to substantially decrease a contribution of multiply scattered light in the backscattered light. The instrument can further comprise a first photon-counting detector positioned to receive the backscattered light from a second end of the fibre, correlation logic responsive to the first photon-counting detector and single-scattering fluid property analysis logic responsive to the correlation logic and operative to derive at least one fluid property for the sample fluid.
