    摘要： An imaging system for generating an image of an object is provided. The imaging system comprises an X-ray source disposed in a spatial relationship to the object configured to transmit X-ray radiation through the object. The system further comprises at least one X-ray detecting media configured to convert the X-ray radiation transmitted through the object to optical signals. In addition, the system comprises an optical transmission conduit comprising a first end and a second end and an optical detector configured to convert optical signals to corresponding electrical signals. The first end of the optical transmission conduit is coupled to the X-ray detection device and the second end coupled to the optical detector.

    摘要： The invention provides novel “folded” Mach-Zehnder interferometers (“folded” MZI's), methods for making folded MZI's, and systems and devices incorporating them. The novel folded MZI's are elaborated from conventional MZI structures by cutting across the interferometer arms of a conventional MZI structure and creating reflectors on the exposed ends of the interferometer arms to form two “folded” MZI's from a single conventional Mach-Zehnder interferometer structure. The novel folded MZI's show promise as sensors having a reduced size and enhanced sensitivity relative to sensors incorporating conventional Mach-Zehnder Interferometers.

    摘要： A method for determining deflection of an optical sensor having an optical cavity includes: providing an optical signal including a train of time spaced light pulses, each light pulse including a known set of wavelengths; splitting the optical signal and providing a portion of the optical signal to a reference path; detecting light pulses in the portion of the optical signal; using a remaining portion of the optical signal and interrogating the sensor; receiving a reflected optical signal from the sensor; detecting light pulses in the reflected optical signal; and analyzing the portion of the optical signal and the reflected optical signal to determine the deflection. Corresponding apparatus and computer program products are provided.
