    Abstract: The present invention provides an optical analysis system for determining an amplitude of a principal component of an optical signal. The principle component is indicative of the concentration of a particular compound of various compounds of a substance that is subject to spectroscopic analysis. The optical signal is subject to a wavelength selective weighting. Spectral weighting is preferably performed by means of spatial light manipulation means in combination with a dispersive optical element. The inventive calibration mechanism and method effectively allows for an accurate positioning of the spatial light manipulation means. Calibration is based on a calibration segment on the spatial light manipulation means in combination with a reference light source and a detector.

    Abstract: An apparatus for generating artificial light that closely simulates the intensity and spectrum of natural light and other dynamic light conditions. The apparatus includes a collection of light sources of various colors which are controlled by a computer. Attached to the computer is a sensor that measures the spectral qualities of the light produced by the light sources. The sensor sends this information to the computer which then adjusts the light sources to generate the desired light conditions.

    Abstract: The invention relates to a procedure for determining an identification of a sample of material, or its properties. Electromagnetic radiation from a radiation source (1) is reflected or transmitted through the sample. The radiation from the sample is collected and analyzed over several channels (7, 7', 7"), which modulate the radiation with a spectral transmission function which is unique for each channel. The modulated radiation is transmitted to one or several detectors (9, 9', 9") which produce output signals which are further electronically processed. The spectral range of each of the individual channels is common to all of the channels. Within the common range the channels are provided with different spectral transmission functions (7, 7',7") which are optimally chosen for a given application.

    Abstract: In an optical filter to be used for signal selection, removal of noise, equalizing the wavelength of signal light, etc. in an optical communication system, optical measurement device or the like, and in an optical amplifier employing such optical filter, signal light is dispersed at different angles according to each wavelength by a diffraction grating and the dispersed light is selectively transmitted or reflected by a transmission type spatial filter or reflection type spatial filter, and is then coupled with an output fiber bundle as non-dispersed light by the diffraction grating. Thus, the optical filter has variable wavelength pass band characteristics and the optical amplifier possesses a uniform wavelength amplification factor.

    Abstract: An optical arrangement for use in spectrometry uses a masking device which eliminates unwanted spectral regions prior to optically resolving the unmasked information. The optical arrangement comprises an entrance slit to select incidence spectral energy from an energized source and a concave grating of relatively low dispersion to image the spectrum of the entrance slit onto a stationary mask which simultaneously selects spectral regions of the dispersed incident spectral energy. The selected spectral regions are collimated and recombined and directed onto an Echelle grating to disperse with high resolution the selected spectral regions. A concave mirror focuses the dispersed selected spectral regions into a focal plane of highly resolved spectral energy which can be detected to determine the spectral information coming from the source. The optical arrangement is particularly well suited for use with narrow spectral bandwidth spectral information distributed over a large spectral range. In spectroscopy, desired information very often occupies a tiny fraction of the total spectral information presented to a spectrometer. With this optical arrangement, spectral information can be selected from a much broader band spectral information and collected with high resolution on a small curvilinear portion of the output focal plane. The arrangement is particularly useful for absorption, light scattering or emission spectroscopy. It provides a stable mechanical design making it less sensitive to vibration. Manufacturing mechanical tolerances are also less restrictive.

    Abstract: A filter for removing coherent radiation from a source in a field of view, substantially independent of the size of the source, comprises a first reticle 22 located in the path of received light 21, a first lens 23 producing an optical transform of the first reticle 22 at a second reticle 24 located in the image plane of the first lens 23, a second lens 25 producing an optical transform of the second reticle 24 and a third reticle 26 located in the image plane of the second lens 25. The arrangement is such that the spatial transmittance of the third reticle 26 is selected to block at least part of the diffracted image of the first reticle 22 produced in the image plane of the second lens 25 and characteristic of the coherent radiation. Preferably the optical transforms are Fourier Transforms. A monochromatic coherent source in the field of view produces a pattern of diffracted energy in the image plane of the second lens which is independent of the size of the source. Thus, by providing a suitable reticle 26 in the image plane of the second lens light from a coherent source in the field of view can be blocked while polychromatic light is transmitted. The first and second reticles may be periodic picket-fence reticles or different spatial frequencies may be used for the first and third reticles so as to vary the stop-band characteristics of the filter.
