    摘要: A method for increasing the throughput, or the precision, or both the precision and the throughput, of a flow cytometer, or of a hematology analyzer employing a flow cytometer, and for further reducing the complexity of such a cytometer or analyzer, by utilizing the technique of laser rastering in combination with a lysis-free single-dilution method. Laser rastering involves sweeping a laser beam across a flowing sample stream in a hematology analyzer. A lysis-free single-dilution method involves performing all the flow cytometer measurements on a sample using a single aliquot, a single lysis-free reagent solution, a single dilution, and a single pass of said dilution through the measurement apparatus. An apparatus suitable for carrying out the method of this invention comprises an optical module comprising a source of light, a scanning device, a lens or system of lenses, a flowcell, detectors, and filters; and an electronic module comprising preamplifiers, analog signal conditioning elements, analog-to-digital converters, field-programmable gate arrays, digital signal processing elements, and data storage elements.

    摘要: A waveguide under test can be exposed to a light signal whose polarization rotates between the vertical and horizontal polarizations. The intensity detected at a photodetector can be separated into AC and DC components. The AC components may be utilized to derive a characteristics which is indicative of birefringence of the waveguide. If the light signal is scanned over the waveguide under test, a measure of the birefringence at each position along the waveguide may be determined.

    摘要: An optical network may include a detector for detecting the power of each of a plurality of channels of a wavelength division multiplexed optical signal in one embodiment of the present invention. Each channel may be conveyed to an interface underneath a detector by way of a core formed in the substrate. The interface may include a trench with one side surface angled to form a reflector to reflect light upwardly to be detected by the detector. The trench may be filled with a convex microlens.
