摘要： Grains are put into a test tube containing a specific reagent solution and are stirred to produce a reactive solution and this solution is put into a cell. A light is irradiated to the cell to detect an absorbance at a wavelength where the absorbance reaches a peak and an absorbance in a wavelength region in which the absorbance hardly varies. Then, freshness of the grains and beans is judged based on a difference between the two absorbances.

摘要： A method and apparatus for the quantitative determination of optically active substances includes two light-emitting diodes, each with a respective collimator lens and polarization filter, a cell filled with dialysate, an analyzer, a detector and measurement and evaluation electronics. The clocked light of the light-emitting diodes is linearly polarized by the polarization filters. The polarization directions differ by a few degrees. The polarization direction of the analyzer is aligned essentially perpendicularly relative to the polarization filters, such that the radiation of the two light-emitting diodes passing through an optically non-rotating dialysate generates the same photosignal in the detector. The polarization of the radiation passing through an optically rotating dialysate, by contrast, is rotated farther in the same direction, so that the detector receives two different photosignals from the light-emitting diodes from which the concentration of optically active substances can be deduced on the basis of comparison. The cell has a chamber filled with a reference fluid, through which the radiation of the two light-emitting diodes passes. The passing through the reference fluid radiation is registered with a further photodiode and is compared for an automatic signal balancing.

摘要： A fiber optic fluid opacity sensor includes a light source (12) transmitting light to dividing means (14) for providing a sample light signal (18) and a reference light signal (20) to dual photodetectors (26, 28). Sample and reference optical pathways (19, 21) are defined by optical fibers (18, 20) spaced apart from and axially aligned with the photodetectors (26, 28) at a predetermined distance. Signal processing means (30) takes the log ratio output of the signals from the photodetectors (26, 28) for cancelling the effect of light source drift since the same source (12) is common to both for measuring the light transmission and determining opacity therefrom. A sample probe (40) contains the photodetectors (26, 28) and the sample and reference optical pathways (19, 21). The light source (12) and the signal processing means (30) are situated outside of the probe (40) and by virtue thereof outside of the sample process line (48).

摘要： An apparatus is provided for obtaining spectral information and quantifying the physical properties of a sample. The apparatus comprises a light source and a high-efficiency fiber optic switch means communicating with the light source for directing the light alternatively along at least two channels, the two channels comprising at least one reference channel and at least one sample channel. A sample means communicates with the sample channel for providing an interface between the light and the sample. A fiber optic means comprising a high-efficiency fiber optic switch and/or an optical coupler communicates with the sample channels and the reference channels and directs the light alternatively from the reference and sample channels to a mode scrambler. A wavelength discrimination device separates the light from the mode scrambler into component wavelengths and provides spectral information for the determination of the physical properties of the sample. The apparatus of the present invention provides superior chemometric prediction accuracy, is reliable, durable, and stable over time, and provides outstanding performance in a manufacturing or field environment.

摘要： A comparitive colorimeter for use in the field which simultaneously compares the color densities of two liquid samples and designates the degree of difference. The apparatus includes two major subsystems, optical and electronic. The optical subsystem is designed to provide identical light beams through both the sample and standard solutions and to minimize the effect which imperfect sample tubes have on the output. The electronic subsystem includes a log conversion and differential amplifier circuit for generating a difference signal representative of the difference between the optical densities of the sample and standard solutions. The difference signal is evaluated by a comparative circuit consisting of a resistive chain having a plurality of node voltages and hex inverters connected to the node voltages. The hex inverters drive a series of LED indicator lights to designate the relative degree of difference between the optical densities of the sample and standard. A correction circuit is provided for referencing the difference signal to the threshold voltage of the hex inverters and for compensating for initial differences in the optical paths of the sample and standard solutions.
