Abstract: A miniaturized spectrometer is adapted for placement within a body near tissue to be characterized. The spectrometer includes a light source and a plurality of light detectors. The light source generates light to illuminate the tissue. The detectors detect optical signals from the illuminated tissue and convert these optical signals to electrical signals. The miniaturized spectrometer can be disposed at the distal end of an interventional device. Optical conduits, such as fiber optic cables or strands, extending the length of the interventional device are not required when the miniature spectrometer is employed.

Abstract: The present invention concerns an LED spectrometer operating without moving parts according to the sweep principle, and appropriate to serve as a structural component in many kinds of spectroscopic concentration analyzers. The design of the invention affords the advantage that, even at its minimum, the optical power of the LED spectrometer of the invention is about fivefold compared with the designs of prior art. Furthermore, improvement of the efficiency of the LED radiation source and of that of the optics has brought a multiple augmentation in power to the wavelength spectrum sent out by the radiation source. In the design of the invention, concentrators (6) of non-imaging type are used to collimate the wavelength spectrum emitted by the LEDs (3).

Abstract: A method for spectral measurement is disclosed. The method uses a low-resolution grating to disperse light and thereby image a spectrum thereof. The imaged spectrum is converted into a digital electrical signal and is processed in order to enhance the spectral information. The resulting spectral information is analogous to that captured using a higher resolution spectral imager with optical processing of the spectral data. The method is equally applicable to enhancing resolution of spectra captured using high resolution spectral imaging devices.

Abstract: A device for compensating the birefringence normally associated with an integrated optical waveguide grating device has a polarization compensating slab waveguide region. This compensating region can be provided within the slab waveguide region normally present in the grating device by etching, doping, ion implanting a sub-region of a predetermined shape and dimension to change its birefringence. Alternatively, or in combination with changing the birefringence in this sub-region, electrodes can be provided for electro-optically changing the birefringence dynamically as required. This device can be applied to reflective and transmissive diffraction gratings and to phased array waveguide gratings.

Abstract: A spectrograph usable as a demultiplexer/detector in a wavelength division multiplexing optical system. The spectrograph comprises a planar waveguide and a detector array. The planar waveguide has a dispersive edge having an inwardly concave shape, an input edge, and a straight output edge. The dispersive edge has a reflective diffraction grating formed on it, the grating having a variable line spacing. An optical input signal comprising a plurality of different wavelength ranges enters the waveguide at the input edge, and travels through the waveguide and strikes the grating. The grating focuses the optical energy in each of the wavelength ranges at a focal spot at the output edge, the position of each focal spot being a function of wavelength. The detector array comprises a plurality of photodetectors positioned along a straight line, such that the photodetectors are positioned at the focal spots. Each photodetector therefore detects the optical energy in one of the input ranges. A stack of such planar waveguides may be assembled to form a multi-channel spectrograph.

A photodetector is provided for detecting the optical level of the optical wave guided, deflected by the surface acoustic wave and radiated out of the optical waveguide. A frequency detector is provided for detecting the frequency of the surface acoustic wave at the time the photodetector detects the optical level of the optical wave guided, deflected by the surface acoustic wave and radiated out of the optical waveguide.
