Abstract: An apparatus for measuring amylose and/or amylopectin content in rice. A near infrared light beam having its wavelength in a range of from about 1900 nm to about 2500 nm is applied to sample rice (5). A detector (26,27,28) receives light reflected from and/or transmitted through the sample rice (5), to generate signals representative of luminous intensity of the received light. A memory device (122) has stored therein content conversion coefficients set for the amylose and/or amylopectin. A calculation device (123) calculates the amylose and/or amylopectin content in the sample rice (5), based on the detecting signals from the detector (26,27,28) and the content conversion coefficients stored in the memory device (122). The calculated content is displayed by a display device (126,127).

Abstract: The optical reflectance or transmittance concentration analyzer includes an acousto-optical tunable filter (AOTF) with a pair of crossed polarizers (3, 5) to select one of the tuned monochromatic light beams that pass from a light source (1) through the AOTF. The AOTF is tuned by a computer controlled digital-to-analog converter (12) through a tunable sweep oscillator (11). To obtain rapid wavelength change along with electronic chopping or wavelength modulation, the digital-to-analog converter output is added to the output of a high speed signal generator (18). The modulated light is conducted directly or through a fiber optic cable to the location of the optical measurement and impinges upon the sample where it is reflected or transmitted. The emerging light is collected onto detector(s) (10). The measurement time interval can be distributed among the required wavelengths or wavelength pairs according to an unequal scheme to decrease the error of the result in a calibration equation. The apparatus is particularly adaptable for use as an on-line concentration monitor in industrial process control because of tis stability, efficiency and ability to perform quick analyses.

Abstract: Optical measurement apparatus includes a cell (12) adapted to receive fluid for testing and a light source (16) arranged to direct an incident light beam (5) into the cell. Means (14) is provided to detect at least a pre-determined portion of light emitted by a segment (13) of the cell transversely of the direction of said incident light beam. The light source (16) and the cell (12) are arranged so that the light incident on the cell is not collimated but, as it traverses said segment of the cell, is confined to the cell by total internal reflection, unless otherwise scattered by particles in the cell. A corresponding method is also claimed.

Abstract: A spectroscopic measurement apparatus 1A comprises an integrating sphere 20 in which a sample S is located, a spectroscopic analyzer 30 dispersing the light to be measured from the sample S and obtaining a wavelength spectrum, and a data analyzer 50. The analyzer 50 includes an object range setting section which sets a first object range corresponding to excitation light and a second object range corresponding to light emission from the sample S in a wavelength spectrum, and a sample information analyzing section which determines a luminescence quantum yield of the sample S, determines a measurement value ¦ 0 of the luminescence quantum yield from results of a reference measurement and a sample measurement, and determines, by using factors ², ³ regarding stray light in the reference measurement, an analysis value ¦ of the luminescence quantum yield with the effect of stray light reduced by ¦ = ²¦ 0 +³. This realizes a spectroscopic measurement apparatus, a measurement method, and a measurement program which can reduce the effect of stray light generated in a spectrometer.
