    Abstract: The invention relates to a method for controlling flat glass forming by flowing a molten glass over a liquid tin layer contained in a forming vat wherein a forming characteristic quantity is measured above the glass surface during forming by means of beams generated by at least one absorption spectroscopy-based analyser, wherein the light beams generated by said analyser form a net above the glass surface. A device for carrying out the inventive method comprising an arm for supporting a vessel which comprises a retroreflecting means for receiving a light beam and transmitting it in an opposite direction parallel to an incident optical path is also disclosed.

    Abstract: Optical gas analyzers are disclosed for analyzing gas samples, including a source of radiation, a gas sample cell through which the radiation passes, a mirror for dividing that radiation into a number of secondary radiation paths for each of the gases in the gas sample which is to be analyzed, with the mirror being arranged so that after a single reflection from the mirror each of the secondary radiation paths is directed to an optical filter which passes a preselected wavelength characteristic of the particular gas in question, and then to a detector for measuring that wavelength characteristic. These optical gas analyzers are preferably used in connection with gas samples which include anesthetic gases, along with CO.sub.2 and N.sub.2 O.

    Abstract: In an optical instrument, a fiber optic probe is provided to irradiate a sample with visible NIR and ultraviolet light. Glass fibers carry the visible and NIR light to the probe from a visible and NIR light source and quartz fibers carry ultraviolet light to the probe from an ultraviolet source. Glass fibers carry visible and NIR light emanating from the sample to a spectrometer having a fixed grating and an array of photodetectors to receive the spectrum dispersed by the grating within the spectrometer housing. Amplifiers are also contained in the spectrometer housing severally connected to the photodetectors to amplify the output signals of the photodetectors. The probe is provided with a standard white sample pivotal into position to receive the light from the visible light source. A computer is programmed to provide automatic calibrating whenever the temperature within the housing changes more than a predetermined small amount. The automatic calibration is carried out by pivoting the white standard into position and computing calibration values from the resulting photodector outputs. Automatic calibration is also provided when the ratio of output signals from selected ones of the photodetectors changes by more than a predetermined small percentage.

    Abstract: A method and system are presented for use in measuring one or more characteristics of patterned structures. The method comprises: performing measurements on a patterned structure by illuminating the structure with exciting light to cause Raman scattering of one or more excited regions of the pattern structure, while applying a controlled change of at least temperature condition of the patterned structure, and detecting the Raman scattering, and generating corresponding measured data indicative of a temperature dependence of the detected Raman scattering; and analyzing the measured data and generating data indicative of spatial profile of one or more properties of the patterned structure.
