Abstract: An optical device includes an optical waveguide through which light propagates and a micro-resonator structure including an optical sensor. The micro-resonator is configured to resonate at a wavelength of light that may be transmitted through the optical waveguide. When light at that wavelength is transmitted through the optical waveguide, it resonates in the resonator and is detected by the optical sensor to produce an electrical signal. The optical resonator may be a micro-cylinder, disc or ring resonator and may be coupled to the waveguide via evanescent coupling or leaky-mode coupling. Multiple resonators may be implemented proximate to the waveguide to allow multiple wavelengths to be detected. When the waveguide is coupled to a tunable laser, signals provided by the optical sensor may be used to tune the wavelength of the laser.

Abstract: A curved mirrored surface is used to collect radiation scattered by a sample surface and originating from a normal illumination beam and an oblique illumination beam. The collected radiation is focused to a detector. Scattered radiation originating from the normal and oblique illumination beams may be distinguished by employing radiation at two different wavelengths, by intentionally introducing an offset between the spots illuminated by the two beams or by switching the normal and oblique illumination beams on and off alternately. Beam position error caused by change in sample height may be corrected by detecting specular reflection of an oblique illumination beam and changing the direction of illumination in response thereto. Butterfly-shaped spatial filters may be used in conjunction with curved mirror radiation collectors to restrict detection to certain azimuthal angles.

Abstract: A spectrometer apparatus for determining an optical characteristic of an object or material is disclosed. A probe is positionable to be in proximity to the object or material. First and second receivers are provided on the probe. Light from one or more first receivers is coupled to one or more first optical sensors via a spectral separation implement. Light from one or more second receivers is coupled to one or more second sensors without spectral separation of the light. A light source provides light to the object or material via the probe. A processor coupled to receive one or more signals from the first and second sensors determines the optical characteristic of the object or material and determines a physical position property of the probe with respect to the object or material or a non-color optical property of the object or material. The physical position property may be a distance or angular position of the probe with respect to a surface of the object or material. The non-color optical property may be translucence, gloss, gray level and/or surface texture.

Abstract: An apparatus and method capable of providing spatially multiplexed IR spectral information simultaneously in real-time for multiple samples or multiple spatial areas of one sample using IR absorption phenomena requires no moving parts or Fourier Transform during operation, and self-compensates for background spectra and degradation of component performance over time. IR spectral information and chemical analysis of the samples is determined by using one or more IR sources, sampling accessories for positioning the samples, optically dispersive elements, a focal plane array (FPA) arranged to detect the dispersed light beams, and a processor and display to control the FPA, and display an IR spectrograph. Fiber-optic coupling can be used to allow remote sensing. Portability, reliability, and ruggedness is enhanced due to the no-moving part construction. Applications include determining time-resolved orientation and characteristics of materials, including polymer monolayers. Orthogonal polarizers may be used to determine certain material characteristics.

Abstract: A common aperture, multi-mode optical imager for imaging electromagnetic radiation bands from a field of two or more different wavelengths is described. Fore-optics are provided to gather and direct electromagnetic radiation bands forming an image into an aperture of the multi-mode optical imager. The image is divided into two different wavelength bands, such as visible light and long-wave infrared. The first wavelength band (e.g., visible light) is detected by a first detector, such as a CCD array, for imaging thereof. The second wavelength band (e.g., long-wave infrared) is detected by a second detector, such as an uncooled microbolometer array, for imaging thereof. Additional optics may be provided for conditioning of the first and second wavelength bands, such as such as for changing the magnification, providing cold shielding, filtering, and/or further spectral separation.
