  • A high-resolution lateral displacement sensing

    A method for high-resolution lateral displacement sensing is proposed. The sensor includes an optical transceiver and a piece of reflective sheeting fixed to the object to be measured. The reflector position is measured by illuminating the reflector and focusing the reflected light on a four-quadrant (4Q) position-sensitive detector (PSD).

  • A RP-LC method with evaporative light scattering

    The method involves acidification to neutralise antacid components of the formulation, then a single extraction of the PDMS with dichloromethane. This is followed by separation with a reversed-phase column using an acetonitrile-chloroform solvent gradient, and quantification by an evaporative light scattering detector.

  • Light Obscuration, Optical Particle Detection -

    The gas detector then modulates the emission wavelength of the LD so that the absorption line peak is kept at the center with 10 kHz, and irradiates the laser light to the space. This generates a 1f (10 kHz) component proportional to the light intensity, and a 2f (20 kHz) component via gas absorption if methane exists in the optical path.
