    Abstract: A spectrometer readout system with storage capacitors for temporarily storing output signals generated by a series of photomultiplier tubes that are positioned to monitor selected spectral lines. A voltage-time converter sequentially discharges the capacitors to a preset level and converts the stored voltages into signals that are related logarithmically to a known signal and an unknown signal. The output of the voltage-time converter defines the log discharge time period which is measured and stored by a computer.

    Abstract: A method of simultaneously locating and identifying a plurality of materials within a field of view by comparing the spectral characteristics obtained from systematically scanning the field of view with known spectral signatures of the same materials stored in a memory bank. The number of times a known material is identified as being in the field of view is recorded and referenced to a base. The spectral signatures in the memory bank are continually updated in response to spectral conditions obtained from scanning the field of view.

    Abstract: There is provided a photodetector wherein charging current to a photodiode is integrated to determine an amount of discharge due to conduction of photoelectric current through the photodiode and thereby to measure intensity of photon flux incident to the photodiode, so that linearity of light input intensity versus output voltage characteristics can be improved and dynamic range of the measurement can be extended.

    Abstract: An arrangement of the Rowland character includes a support and a concave grating on the support for producing the spectrum characteristic of a sample being investigated. The support has a series of slits thereon which are positioned on the Rowland circle and are adjusted to the spectral lines of samples to be investigated. An element on the support is provided with a primary slit for directing the radiation derived from a sample being investigated onto the concave grating. The primary slit is positioned on the Rowland circle and the element provided with the primary slit is mounted on the support for movement along the arc of the Rowland circle. The element is mounted in such a manner as to be arrestable in a plurality of positions. The element is favorably in the form of a plate. A preferred embodiment contemplates the provision of a pair of grooves in the support, which latter may be in the form of a housing, with the grooves following the curvature of the Rowland circle and the element being guided in the grooves. The edges of the element located in the grooves may be provided with openings in which there are accommodated spherical members as well as biasing elements for urging the spherical members into contact with the grooves.

    Abstract: An apparatus for measuring the moisture content of a soil sample at selected depths is disclosed. Light is conducted from a source via a fiber optical cable to a soil probe which is inserted at selected depths into a bore hole formed in the soil sample. Light from the source and reflected light from the soil sample is conducted via fiber optic cables to a reflectometer, which determines reflection factors of the soil sample at three selected infrared wavelengths of a water absorption band. Means are provided to compute the moisture content of the sample at the selected depths from the measured reflectance factors.
