Abstract: A rotary spectrometer including a plurality of input ports. Each input port may be arranged to receive an optical waveguide carrying electromagnetic radiation. The spectrometer also includes a plurality of optical bandpass filters, which are housed on a first body that rotates under the control of a motor so that each optical bandpass filter may be brought into alignment with each input port. Further, the spectrometer includes a plurality of detector circuits disposed on a second body that rotates with the first body. Each detector circuit is optoelectrically coupled to one of the plurality of optical bandpass filters, thereby resulting in each detector circuit being dedicated to responding to a range of wavelengths determined by the bandpass filter to which it is optoelectrically coupled.

Abstract: A disc serving as a spatial radiation modulator has dispersed radiation filters thereon. Each filter has a transmittance or reflectance modulation function of the form sin2(mnullnullpnullr/4), where m is a positive integer and p has one of the four values 0, 1, 2, 3. A radiation beam including selected wavelength components is diffracted into an elongated image dispersed according to wavelength. Different wavelength components are focused onto different filters on the modulator and are encoded by correspond filters. Since the modulation functions of the filters are orthogonal to one another, it is possible to extract the amplitude of each wavelength component after it has been encoded or modulated by corresponding filter from the total detected signal during one measurement.

Abstract: Spectroscopy apparatus for spectrochemical analysis of a sample having an excitation source (60) for providing spectral light (62) of the sample for analysis. The spectral light (62) is analysed via an optical system (64-66-68) that includes a polychromator (70, 74-80) and solid state multielement array detector (82). The elements (i.e. pixels) of the detector (82) are serially reel by means (84) to provide light intensity measurements as a function of wavelength. A problem is that the elements (pixels) of the detector (82) continue to accumulate change during the serial read-out. This is avoided by providing an optical shutter (72) for blocking the spectral light (62) whilst elements (pixels) of the detector (82) are being serially read. Shutter (72) has a piezoelectric actuator which is preferably a bimorph mounted as a cantilever. It is preferably located adjacent to the entrance aperture (70) of the polychromator. Bimorph structures for the actuator and drive and protective circuit arrangements are also disclosed.

Abstract: A micro spectrophotometer is monolithically constructed on a silicon substrate. The spectrophotometer includes a concave grating, which is used for dispersing optical waves as well as focusing reflected light onto a photodiode array sited on a silicon bridge. The silicon bridge is bent 90° from the surface of the silicon substrate in order to orthogonally intersect the output light from the grating. A precision notch is defined in the silicon substrate for coupling to an optical input fiber. Signal processing circuitry is etched on the substrate using conventional CMOS processes for initial processing of information received from the photodiode array.

Abstract: An imaging system for obtaining an image of a field-of-view where high levels of light from an extraneous source may be present at one area and low levels of light present at other areas in the field-of-view. The imaging system has a lens to focus an image of the field-of-view onto a surface of a photodetector and an optical limiter is located between the lens and the photodetector. The optical limiter limits transmission of the high levels of light at areas onto which those are focussed by the lens but remains transmissive to the low levels of light at other areas. The imaging system is particularly intended for use in laser warning receivers where sunlight may be focussed on the optical limiter and blocked at the particularly area on which it is focussed, the optical limiter remaining transmissive to laser beams, even if intense, at locations other than where the sunlight is focussed allowing laser beams to be detected by the photodetector.

Abstract: Percentage concentrations of constituents or color components of a sample are determined using a spectral analyzer with a wide illumination spot size and detector. The analyzer irradiates the sample, picks up diffuse reflectance of individual wavelengths from the sample and spatially separates the diffuse reflectance into a response at individual wavelengths. The result is to simultaneously detect the intensities of the individual wavelengths in parallel from the sample being analyzed. Percentage constituents of a composite substance can be determined or, alternatively, the components of color in a sample can be determined by analyzing wavelengths of reflected light.

Abstract: A spectrum analyzing system measures or analyzes the colorimetric properties of a test sample at a preselected wavelength or range of wavelengths within the ultraviolet, visible, and near infrared regions. The system includes a spectrophotometer provided with a wideband light source, optical devices providing a sample light path and a reference light path, a chopper wheel allowing light to be directed alternately along the sample and reference paths interspersed with dark periods during which no light travels along either path, a dispersion grating for dispersing the light from both paths, a series of neutral density filters for limiting to various degrees the amount of light traversing each path, and a linear array of photodiodes for detecting the dispersed light at different wavelengths. The system also includes an electronic control section including a programmable power supply for controlling the intensity of light from the light source whereby the combination of the use of the neutral density filters in conjunction with controlling the intensity of light from the light source can be used to operate the photodiode array to prevent operation thereof near the saturated and dark current levels, and means for scanning the photodiode array at high speeds during rotation of the chopper wheel to provide a high speed spectral readout.
