    Abstract: A sampling accessory coupled to a hand-held reflectance spectrometer provides expanded sampling area which in turn provides better signal averaging from agricultural products which are often inhomogeneous. The sampling accessory includes a sample site repositioning means and a “sample cup” having a base that is transparent to near IR wavelengths.The hand-held reflectance spectrometer includes a shutter responsive to control signals from the control circuitry. When the shutter is closed, a reference measurement may be made. When the shutter is open, a sample measurement is taken.Sample repositioning and data acquisition within the cup may be performed by several means. Fresh sample regions may be exposed through either manual or motor driven sample cup rotation. Alternatively, the sample may be vibrated to induce fresh sample exposure at the window. A further embodiment includes illumination and/or detection paths that may be altered through electrically driven steering optics.

    Abstract: The present invention concerns a method and camera for obtaining a high-contrast image of a predetermined target present in an area under observation. The method involves obtaining an in-band image of the observation area including the target using a filter whose bands are aligned with selected characteristic wavelength bands of the target and an out-of-band image of the observation area excluding the target using the filter with its bands non-aligned with the selected characteristic wavelength bands of the target. Processing of the in-band and out-of-band images results in a high-contrast image highlighting the presence of the target in the observation area and thereby allowing its detection and monitoring.

    Abstract: An optical characteristic measurement device includes a photodetector and a processor. The photodetector has a detection surface greater than a light incident surface receiving light from a spectrometer. The processor is configured to obtain a measurement spectrum detected in a first detection area corresponding to the light incident surface and a signal intensity detected in a second detection area different from the light incident surface, correct a pattern prepared in advance and exhibiting a noise characteristic of the photodetector based on the signal intensity to calculate a first correction spectrum, subtract a correction value calculated based on the signal intensity from each component value of the measurement spectrum to calculate a second correction spectrum, and subtract each component value of the first correction spectrum from a corresponding component value of the second correction spectrum to calculate an output spectrum.

    Abstract: A processing unit obtains a first spectrum detected in a first detection area and a first signal intensity detected in a second detection area after the light entering the housing is cut off, and then calculates a first correction spectrum by subtracting a first correction value calculated based on the first signal intensity from each component value of the first spectrum. The processing unit obtains a second spectrum detected in the first detection area and a second signal intensity detected in the second detection area while a cut-off portion is opened, and then calculates a second correction spectrum by subtracting a second correction value calculated based on the second signal intensity from each component value of the second spectrum. The processing unit calculates an output spectrum representing a measurement result by subtracting a corresponding component value of the first correction spectrum from each component value of the second correction spectrum.

    Abstract: An optical or infrared spectrometer is suitable for on-line measurements for industrial, agricultural, field, commercial and other applications. Optical spectrometers are very useful for various analytical measurements. On-line operation is needed for obtaining real-time information, which is useful e.g. for process automation and quality control needs. The invention is based on optical design optimized for measuring moving samples at a distance and includes a light guide for signal homogenization, a linear variable filter for defining multiple measurement wavelengths as well as a linear detector array for detecting optical signals relating to the different wavelengths. There is an element for cooling and stabilizing the operating temperature of both the linear detector array and the linear variable filter, while the spectrometer is operating in variable environmental conditions. Thanks to the optical signal chain designed to maximize the radiance at the detector, the proposed spectrometer can provide high signal-to-noise ratio and high speed.

    Abstract: The present invention has been accomplished to provide an atomic absorption spectrophotometer capable of obtaining measurement data always in the state where the lowest detection limit performance is optimized, without depending on the frequency of the power supply. In a control program which runs on the microcomputer chip 42 mounted on the atomic absorption spectrophotometer 110, a plurality of lighting periods of the light sources 11 and 12 and extraction periods of the sampling data are memorized, whose lowest detection limit performance are optimized for the frequencies (50 Hz and 60 Hz) of the AC power source for driving the AC motor 22. In using the apparatus, by the control program, the frequency of the power source used in this apparatus is identified, the lighting period and sampling data extraction period corresponding to the identified frequency and the measurement mode that a user of the apparatus has previously set are selected from among a plurality of memorized values, and the appropriate lighting period is set to the hardware (PLD 43). Accordingly, without depending on the frequency, it is possible to obtain measurement data always in the state where the lowest detection limit performance is optimized.
