Abstract: An optical grating is oscillated at a high rate to scan a narrow wavelength band of light through the spectrum dispersed by the grating. The grating is connected integrally with the rotor of a motor, which is energized to oscillate its rotor between selected limits. The direction of rotation of the motor is controlled by an H drive circuit connected to a coil of the motor. The speed of the motor is controlled by a pulse train applied to the motor coil through the H drive. The pulse train has a duty cycle varying inversely with the motor speed. The duty cycle of the pulse train is controlled by a counter which is connected to count high frequency pulses and which is reset each time the grating rotates through an angular increment. The limits of the oscillation of the grating and the rate of rotation of the grating between the limits are selectively variable. Output readings from the spectrophotometer are taken at equal angular increments of the grating and these readings are converted to values occurring at equal wavelength increments by a computer.

Abstract: A manual device for the detection of photometric values on a printed product comprises a measuring head extruding from a housing into a measuring position. The measuring head is mounted together with its optical components on a measuring carriage, which may be displaced along the bottom of the housing by means of a drive motor between a rest position and a measuring position. The drive motor drives via a gear, a drive pulley and a grid axle for a monochromator. A sliding gear and a locking device are coordinated with the drive pulley, with the locking device immobilizing the measuring carriage precisely in the measuring position. The drive motor serves to displace the measuring carriage until the locking process essentially begins; and after this process, serves to rotate the grid axle.

Abstract: Apparatus for detecting an anomaly, (e.g. the presence of a hydrocarbon seep) at or near a water or land surface comprises means for generating a beam, preferably a pulsed beam, of primary light radiation, preferably ultra-violet light, and directing the beam towards the surface. The beam is sufficiently intense and of such a spectral composition that the beam causes the anomaly, if present, to emit secondary light radiation. The apparatus also comprises means for collecting the secondary light radiation, or means for collecting solar induced secondary light radiation, spectral analysis means for analysing the spectrum of the secondary radiation, and a high resolution, multi-element digitizing detector for recovering the analyzed secondary radiation. The detector has a plurality of detection channels positioned across the spectrum of the backscattered primary radiation and emitted secondary radiation, the channels being software configurable and under the control of a digitally addressable computer-operated controller. The concentration of used channels across the plurality of channels is adjustable and increasable in the regions of the spectrum of greatest interest and decreasable in the regions of least interest.

Abstract: Iterative compensation of drift of peak positions of spectral lines is effected in a spectral monochromator including a grating, a detector of spectral fractions of a spectral band, a stepper motor for varying relative orientation of the grating and the detector, and a computer. Computer-defined spectral windows each encopasses a spectral band and has an initial spectral center. Each window is scanned to determine a peak spectral position. Calculation is made for determining a spectral position error of the peak position from the initial center for each corresponding window. A functional average of the offsets for the peaks is calculated as a linear function of window position, and a revised spectral center for each window is calculated as being equal to the initial center plus the functional average for the window position determined from the linear function. Each window is shifted correspondingly. The step of successively scanning through each window is repeated to determine a new peak position for each corresponding band, whereby each new peak position is maintained near the spectral center of each corresponding window.

Abstract: A method for determining parameters, especially pressure, temperature, concentration, number of particles and particle size distribution, of gaseous substances present in combustion processes and other high temperature processes, comprises transmitting spectrally broad-band light through an object (2) of measurement, spectrally dividing the light transmitted through said object, and recording the spectral distribution of the light in the studied wavelength range a large number of times. Each recording occurs sequentially in that the spectrally divided light is swept relative to a one-channel detector and for such a short time that the total light intensity of the entire wavelength range is constant during each recording. After that, the mean value of said recorded spectral distributions is generated, and the required parameters are calculated on the basis of said mean value spectral distribution, the appearance of said means value spectral distribution, as well as spectra calculated or recorded for known conditions, being utilized for said calculation.An apparatus comprises means for carrying out the method.

Abstract: An improved rapid-scan spectrophotometer with an optical grating continuously rotating at a constant angular velocity. An optical trigger actuated by the rotating turntable supporting the grating, actuates an analog to digital converter to sample at discrete times an output signal from the sample detector over the desired wavelength range and to store the digitized information in a direct memory access (DMA) buffer. The information may be retrieved as desired from the buffer for further processing or permanent data storage. With each revolution of the optical grating, the range (typically 15.degree.) of wavelengths from the grating that provides useful information is sampled by the analog to digital converter and stored in the buffer. Because the grating is continuously rotating at a constant angular velocity and is not limited by the inertia of optical components, the spectrophotometer can be operated at a much higher scanning speed than an oscillating or vibrating grating spectrophotometer.
