    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: A spectral reflectance sensor including: a light source for emitting a modulated beam of red light; a light source for emitting a modulated beam of near infrared light; a receiver for receiving reflected light produced by either the red source or the near infrared source; a receiver for receiving incident light from either the red source or the infrared source; a signal conditioner responsive to the modulation such that the signals produced by the receivers in response to reflected and incident light from the source can be discriminated from signals produced by ambient light; and a microprocessor having an input such that the microprocessor can determine the intensities of incident red light, reflected red light; incident near infrared light; and reflected near infrared light. From these intensities, and by knowing the growing days since emergence or planting, the sensor can calculate the mid-growing season nitrogen fertilizer requirements of a plant.

    Abstract: Disclosed herein is an apparatus including a structure containing a multiphase fluid and having a transparent window. A collimated light source emits light through the transparent window structure at a wavelength at which a component of a desired phase of the multiphase fluid is absorptive. A photodetector is positioned such that the emitted light passes through the multiphase fluid in the structure and out through the transparent window structure to impinge upon the photodetector. The photodetector has an actual dynamic range for light detection. Processing circuitry adjusts a power of the collimated light source in a series of steps dependent upon a relationship between an output level of the photodetector and a threshold to cause measurement of the emitted light over an effective dynamic range greater than the actual dynamic range. Properties of the multiphase fluid are determined as a function of the measured emitted light.

    Abstract: An apparatus for optically inspecting an at least partially reflecting surface of an object includes first and second transverse carriers (12, 14) defining respective substantially circular segment-shaped cutouts (32). The transverse carriers (12, 14) are disposed at a longitudinal distance (D) from one another and the longitudinal distance (D) defines a longitudinal direction (17). A plurality of longitudinal members are configured to hold the first and second transverse carriers at the longitudinal distance (D). The longitudinal members are arranged at a defined radial distance to the circular segment-shaped cutouts. A translucent diffusing screen is held in the circular segment-shaped cutouts by the transverse carriers to form a tunnel-shaped inspection space. A multiplicity of light sources are arranged outside of the tunnel-shaped inspection space behind the diffusing screen. The light sources are configured to be controlled individually or in small groups to generate variable light-dark patterns on the diffusing screen. A workpiece receptacle is configured for accommodating the object in the tunnel-shaped inspection space. At least one camera is directed into the tunnel-shaped inspection space. An evaluation and control unit is configured to control the light sources and the camera to generate various light-dark patterns on the diffusing screen and to record and evaluate a plurality of images of the object in dependence on the light-dark patterns.
