摘要： An optical probe is for measurement of light transmission of liquid. A tubular housing three equally configured legs defining three arcuately spaced openings in the housing wall. A solid cylindrical member formed of glass or fused silica has a flat transparent end surface and an opposing curved surface silvered to form an internally concave reflector. The cylindrical member is retained in the housing with the transparent end surface adjacent to the openings. A transparent rod member has a flat first end surface and a flat second end surface parallel to the first end surface. The rod member is retained in the housing with the second end surface adjacent to the openings and spaced from the transparent end surface parallel thereto so as to define a cavity therebetween such that, upon immersion of the probe, liquid passes through the openings into the cavity. The first end surface is spaced from the concave reflector so that conjugate focal spots of the concave reflector are located at the first end surface. Two first optical fibers are affixed respectively to the focal spots. Light entering through one optical fiber passes twice through the liquid in the opening while being reflected by the concave reflector into the other optical fiber.

摘要： A probe for use in spectroscopic analysis comprises an optical fiber with a rod-like end piece. One form of the probe has a local detector which can be deposited on the end piece or located close to it. This improves collection efficiency of radiation diffusely scattered from a sample being investigated. An alternative arrangement uses a local source of radiation.

摘要： In optical device for measuring displacement an optical grating is formed of alternating transparent and opaque stripes having equal widths. The grating is in an aperture plane with the stripes parallel to a central plane that is perpendicular to the aperture plane. Respective subpluralities of the stripes are located in an aperture area in the aperture plane, so that incident light rays on the aperture area are at least partially passed as beams by the transparent strips in the aperture area. A concave mirror has it center of curvature at the aperture area so as to return the beams back to the aperture area. The return beams are further passed by the transparent strips in the aperture area as return light. The grating is displaceable laterally to the cental plane, such that a corresponding responsiveness of the return light intensity to the lateral position provides a measure of displacement of the grating relative to the central plane. Alternative device with reflecting strips function similarly.

摘要： In a method and a system for analyzing spectral data including a spectrophotometer and a spectral detector, a data station receives first transmittance spectrum data points and has a file register containing second transmittance spectrum data points. The first and second transmittance data points are transformed respectively to set of first and second absorbance spectrum data points. The first and second absorbance points are band pass filtered at a characteristic frequency nominally associated with spectral bandwidth so as to produce respective sets of first and second filtered data points. A set of weighting factors are established, each corresponding to the square of the sum of a first transmittance point and a second transmittance point for a selected frequency. A comparison factor is generated as a normalized sum of products over a selected spectral frequency range, each product being formed of a weighting factor and corresponding first and second absorbance data points for each selected spectral frequency.

摘要： Standardization is achieved for FTIR spectrometric instruments that effect an intrinsic distortion in spectral information, the distortion being associated with an aperture size. An idealized function of spectral line shape is specified. With a small calibration aperture, spectral data is obtained for a basic sample having known "true" spectral data, and standard spectral data also is obtained for a standard sample. With a larger, normal sized aperture, standard spectral data is obtained again for the calibration sample. A transformation factor, that is a function of this data and the standardized function, is applied to spectral data for test samples to effect standardized information. In another embodiment, the standard sample has known true spectral data, and the basic sample is omitted. In either case, the transformation factor is applied to the sample data in logarithm form, the antilogarithm of the result effects the standardized information.

摘要： A mounting arrangement for accurately orienting an optical component (10) with respect to an axis comprises three mounting elements arranged at the apices of a triangle, one of said mounting elements (16) is fixed whilst the other two (18, 29) are each provided on a pivotable mounting member 20.

摘要： An optical switching device includes a first optical fiber terminating in a first window, and a plurality of second optical fibers each terminating in a corresponding second window. A concave mirror is selectively positionable with conjugate foci located respectively at the first window and selectively at any one of the second windows so as to reciprocally image the first window and a selected second window on each other. The imaging mirror is rotated about an axis spaced from and parallel to the optical axis of the mirror, so as to rotate the mirror among a plurality of arcuately spaced selected positions. In each selected position the imaging means closes a light circuit between the first optical fiber and a selected second optical fiber.

摘要： A method identifies components in a sample by spectrally analyzing the sample in a spectrophotometer. The sample data points output from the spectrophotometer are detected in a detector before being stored in an array in a data station. A preselected smoothing bandwidth is entered into the data station from a keyboard. The bandwidth is converted to a strength parameter; and thereafter each of the smoothed data points is stored before being output as an array of smoothed data points to form a modified spectral display, which identifies the components in the sample.

摘要： A preamplifier network or circuit for converting non-linear signal information, such as is produced by a mercury cadmium tellurium (MCT) detector, to a substantially linear voltage signal output corresponding to the incident light levels on the MCT detector. Conceptually speaking, the subject preamplifier functions as a constant-voltage variable-current source to the MCT detector, and incorporates positive feedback for being effective as a negative resistance to nullify the MCT detector resisance introduced signal component of the signal information being monitored.
