Abstract: A wavelength correction apparatus automatically corrects a deviation of a testing wavelength from a reference spectrum analyzer installed on-site. The apparatus is constructed of a reference light source 62 for outputting a reference light of a specific wavelength; a light input terminal 50 for inputting a testing light whose wavelength is to be measured and compensated; an optical switch 54 for receiving the testing light and the reference light so as to output one either the testing light or the reference light; a control section 60 for controlling the operations of the reference light source 62 and the optical switch 54; and an optical spectrum measuring device 58 for measuring optical spectra output from the optical switch 54 and for operating the control section 60 at a point in time specified by an operator. The in-situ wavelength correction device produce precise compensates for wavelength deviation so that a compact wave correction apparatus can be used on-site of optical communications stations.

Abstract: A spectrometer (10) includes a two-dimensional array of modulatable micro-mirrors (18), a detector (20), and an analyzer (22). The array of micro-mirrors is positioned for receiving individual radiation components forming a part of an input radiation source. The micro-mirrors are modulated at different modulation rates in order to reflect individual radiation components therefrom at known and different modulation rates. The micro-mirror array combines a number of the reflected individual radiation components and reflects the combined components to the detector. The detector is oriented to receive the combined radiation components reflected from the array and is operable to create an output signal representative thereof. The analyzer is operably coupled with the detector to receive the output signal and to analyze at least some of the individual radiation components making up the combined reflection. By using a micro-mirror that receives individual radiation components and then modulates the radiation components at different rates, all of the radiation components can be focused onto a single detector to maximize the signal-to-noise ratio of the detector. A variable band pass filter spectrometer, variable band reject filter spectrometer, variable multiple band pass filter spectrometer, and a variable multiple band reject filter spectrometer utilizing the same invention are also disclosed.

Abstract: In a monochromator including a light dispersing element rotatable about an axis, a linear motor for rotating the light dispersing element around the axis, an encoder for generating a signal representing a rotational position of the light dispersing element, and a linear motor controller for detecting the rotational position of the light dispersing element based on the signal generated by the encoder, the inventive monochromator is characterized in that the signal generated by the encoder has a waveform including no flat portion. That is, the strength of the signal must change if the rotational position of the light dispersing element changes even slightly. Using a linear motor as a driving unit for the light dispersing element, the monochromator of the present invention can rotate the light dispersing element constantly with a stable speed even at high speed. And using such an encoder, the detecting accuracy of the rotational position of the light dispersing element is much improved compared to conventional ones. Thus a spectrophotometer using the inventive monochromator has a better efficiency and accuracy both in the wavelength scanning analysis and in the time course analysis.

The light source provides at least two high intensity peaks at distinct wavelengths. The method comprises scanning a first wavelength region comprising at least one of said at least two high intensity peaks, and measuring the intensities at a selected number of points during the scan. A first of said at least two peaks is coarsely located. A wavelength region around each of said at least two peaks is scanned, measuring the intensities at closer intervals than previously. At least two peaks are located by autocorrelation. The location of said peaks is determined in terms of a distance from a reference point, said distance corresponding to said displacement of the grating.

Abstract: A focal plane scanner having a front objective lens, a spatial window for selectively passing a portion of the image therethrough, and a CCD array for receiving the passed portion of the image. All embodiments have a common feature whereby the spatial window and CCD array are mounted for simultaneous relative reciprocating movement with respect to the front objective lens, and the spatial window is mounted within the focal plane of the front objective. In a first embodiment, the spatial window is a slit and the CCD array is one-dimensional, and successive rows of the image in the focal plane of the front objective lens are passed to the CCD array by an image relay lens interposed between the slit and the CCD array. In a second embodiment, the spatial window is a slit, the CCD array is two-dimensional, and a prism-grating-prism optical spectrometer is interposed between the slit and the CCD array so as to cause the scanned row to be split into a plurality of spectral separations onto the CCD array. In a third embodiment, the CCD array is two-dimensional and the spatial window is a rectangular linear variable filter ("LVF") window, so as to cause the scanned rows impinging on the LVF to be bandpass filtered into spectral components onto the CCD array through an image relay lens interposed between the LVF and the CCD array.

Abstract: A spectrophotometer measures optical absorption of light by a sample received in a sample cell. An array of optical elements disperses the light over a spectral pattern, and a fiber optic beam splitter splits light at a selected spectral band into a reference component and a test component. Detectors measure the intensity of the reference component and the test component after the test component passes through the sample. The fiber optic beam splitter includes a plurality of strands arranged with first ends terminating in a common circular area. Opposite ends of peripheral strands are collected into a first set that transmits the test component while the remaining strands for a second set that transmits the reference component. Preferably, there is a single, central, large strand surrounded by smaller strands. Two emitters are provided for light of two different types, such as visible and UV. The optical array forms a collimated beam having an inner core of one type of light and an outer shell of the other. Specially constructed optical elements then reflect and refract the collimated beam. A motor drives a mirror to scan the beam across an optical slit positioned in front of the beam splitter to select a desired spectral band.
