Abstract: Method in which, in order to actuate a wavelength-tunable laser diode in a spectrometer, a power-time function is predetermined instead of a current-time function, wherein the laser diode is tuned periodically over a wavelength range in accordance with the power-time function. For this purpose, a current profile (i) with which the laser diode is actuated is determined from the power-time function and measured values of the voltage (u) present at the laser diode.

Abstract: An apparatus for attachment to a vehicle for sensing the organic matter content of soil at a soil scene as it is moved through the soil by the vehicle has a probe including a housing, a light source and a light sensor. The light sensor senses the light reflected from the soil scene and produces an output signal which is related to the organic matter content of the soil at the soil scene. The housing is attached to the vehicle so that as it is moved through the soil the soil scene that is observed by the light sensor is beneath the surface of the surrounding soil and the housing shields the soil scene from ambient light. The apparatus also includes a processor which processes the signal from the light sensor using data predetermined from a particular landscape which includes the soil to be sensed.

Abstract: This invention relates to an optical absorptiometer which is characterized by a light source unit of a broad wavelength having a source of constant energy which is collimated into two light beams, one of which is transmitted through the liquid to be measured, and another beam which is transmitted through a conductor and acts as a reference beam, and a detector unit which contains two photocells, one photocell for measuring the beam transmitted through the liquid to be measured, and another photocell which measures the reference beam, a position in the absorptiometer for optically placing the liquid to be measured between the source unit and the detector unit, and means for measuring the energy difference between the light beams of the measured liquid and the reference beams in terms of absorbance, and means for converting this result to an electrical signal. In the preferred embodiment, the constant energy in the light source is controlled by feedback circuitry; the reference beam is transported by a fiber optic cable to the reference photocell of the detector unit; water condensation on the optical and viewing windows is prevented by means of dry air flow; the electrical signal is displayed and/or relayed to control an operation; and the reference beam is a segment of the original light beam from the source.

Abstract: According to the present invention, oxidized and reduced regions of graphene can be accurately detected in a short time using a terahertz wave so as to measure the conductivity of graphene, and thus the time required to test the conductivity of graphene can be reduced. In addition, when an oxidized region exists in graphene, the oxidized region can be immediately reduced by irradiating an electromagnetic wave thereto so as to increase the conductivity of graphene and thus minimize the time required to restore graphene.

Abstract: A LIBS analyzer and method includes a laser configured to produce a plasma on a sample at a focal point on the sample and a spectrometer responsive to radiation emitted from the plasma and configured to produce an output spectrum. A detector is positioned to detect low intensity pre-firing radiation produced by the laser and reflected off the sample from the focal point. The intensity of the low intensity pre-firing radiation is compared to a predetermined minimum and the laser pump sequence is halted if the intensity of the low intensity pre-firing radiation is less than the predetermined minimum.
