摘要： 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.

摘要： The present invention relates generally to a detection device for a spectrophotometer system, and in particular to a light detection device with an analogue input and a digital output. The object of the present invention is to provide a more accurate detection device, which requires substantially less space for accommodating the detection device in a spectrophotometer. This object is solved by using a successive approximation A/D converter (16) which has internal sample and hold circuits, and which heretofore has been used in the audio industry. This will increase the accuracy of the detection device and make it more resistant against disturbances. It will also decrease the space required for such detection device, down to one third compared to conventional detection devices.

The design of a broadband imagining spectrometer is disclosed that enables direct measurement of the spurious optical background intensity during spectroscopic measurements of a sample. The background is measured on a two dimensional surface coincident with the spectrometer exit plane. The background contribution is used to correct the measurements improving the accuracy of the spectroscopic intensity measurement.

摘要： 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.

摘要： A measurement tool for assessing the wavelength linearity of an optical spectrum analyzer utilizes the linear skirt slope region of the included resolution bandwidth filter. The input wavelength is swept from a predetermined start value to a predetermined stop value, and the associated amplitude is recorded. The insertion loss associated with the system is first determined so that this loss can be removed from the recorded amplitude values. By knowing the skirt slope and the measured amplitudes, the wavelength offset can be determined.

摘要： In an optical measurement probe of the type which incorporates a window configuration suited to on-line process control and other applications this invention provides an improved technique for bonding such a window to probe body or process vessel. In general terms, the improvement arises through the use of a compression ring around the bonding area to maintain a consistent seal. In terms of apparatus, a hollow probe body terminates in a distal end having a flanged portion with an inner and outer wall that extends back into the body. The outer wall of the window is sealed against the inner wall of the flanged portion, with compression material urged against the outer wall of the flanged portion to pressurize the seal between the window and the inner wall of the flanged portion. In the preferred embodiment, the compression material is ring-shaped and exhibits substantially the same thermal expansion coefficient as the window. In the case where a sapphire window is used, titanium or Invar may be used for the compression material. The window may be generally cylindrical though, in the preferred embodiments, cork-shaped or spherical window are used.

摘要： In embodiments, spectroscopic monitor monitors modulated light signals to detect low levels of contaminants and other compounds in the presence of background interference. The monitor uses a spectrometer that includes a transmissive modulator capable of causing different frequency ranges to move onto and off of the detector. The different ranges can include those with the desired signal and those selected to subtract background contributions from those with the desired signal. Embodiments of the system are particularly useful for monitoring metal concentrations in combustion effluent.

摘要： Light having a predetermined wavelength band as issued from a light-emitting diode is launched into a gas absorption cell which is filled with a gas having a plurality of absorption spectra. The light launched into the cell has a plurality of wavelengths absorbed by the gas. The absorption wavelengths are known and their values are preset in a memory in an optical spectrum analyzing section 58. The light passing through the cell is launched into the optical spectrum analyzing section 58, where it receives arithmetic operations to produce an optical spectrum. The optical spectrum analyzing section 58 has a CPU which compares a plurality of wavelengths having dominant absorption in the obtained optical spectrum with the preset reference wavelengths to compute the errors in wavelength measurement. The calibration value is determined on the basis of the average of these errors and the optical spectrum analyzer is accordingly calibrated in wavelength.
