    Abstract: A reflective element for directing an optical signal into a fiber optic sensor having an optical fiber includes a plane containing a sharply defined straight line that separates between a first area of low reflectivity and a second area of high reflectivity. The plane is disposed parallel to a free end surface of the optical fiber so that the free end surface intersects the line of the reflective element, whereby relative movement between the free end surface of the optical fiber and the line in response to a physical change sensed by the fiber optic sensor induces variations in an optical signal reflected by the reflective element through the optical fiber, which variations allow measurement of the physical change.

    Abstract: A spectrometer for analyzing a sample of material utilizing a broad band source of electromagnetic radiation and a detector. The spectrometer employs a waveguide possessing an entry and an exit for the electromagnetic radiation emanating from the source. The waveguide further includes a surface between the entry and exit portions which permits interaction between the electromagnetic radiation passing through the wave guide and a sample material. A tapered portion forms a part of the entry of the wave guide and couples the electromagnetic radiation emanating from the source to the waveguide. The electromagnetic radiation passing from the exit of the waveguide is captured and directed to a detector for analysis.

    Abstract: An optical spectrum analyzer includes a surface elastic wave generator for generating in an optical waveguide a surface elastic wave which has a continuously varying frequency and which diffracts and deflects a guided wave as it travels across the path of the guided wave, which guided wave is introduced as a measured light beam into and travels in the optical wave guide. The measured light beam which has been deflected is emitted from the optical waveguide and detected by a light detector. A modulator turns on and off or modulates the surface elastic wave by repeatedly energizing and de-energizing the surface elastic wave generator, the frequency of the modulation being lower than the continuously varying frequency. A filter receives a signal corresponding to the modulation frequency from the modulator and a signal corresponding to the measured light beam from the detector, and extracts a signal component having the same frequency as the modulation frequency from the signal received from the light detector. The frequency of the surface elastic wave is detected on the basis of the signal component extracted by the filler when the measured light beam is detected by the light detector.
