Abstract: There is presented a multipoint measurement system comprising light sources (1, 2); a plurality of illuminating fibers (5, 6) for transmitting light from the light sources to a sample so as to illuminate a plurality of points of the sample (A, B); a plurality of receiving fibers (8, 9) for collecting light beams including transmitted, reflected, scattered light beams at the plurality of points; a beam selector (10) which comprises a rotatable disk (12) having an aperture for transmitting a light beam collected by one of the plurality of receiving fibers (8, 9) through the receiving fiber (11); and an MCPD (4). When the rotatable disk (12) is rotated so that the aperture is displaced to and stops at a position at which light at the desired channel passes through, it is possible to perform measurement only on the light passing through the corresponding receiving fiber (8, 9, 11). Light at any other channel may be measured by rotating the rotatable disk (12) by a predetermined angle.

Abstract: There is provided spectral discrimination apparatus for use in a scanning optical microscope, the spectral discrimination apparatus comprising dispersive means (31) and frequency selective means including a rotatable disc (36) or discs. The discs are formed with apertures or spiral slots which, on rotation of the disc or discs, controls the frequency of light transmitted by the apparatus. The apparatus includes a detector (39) for receiving light from the frequency selective means. The, or each, rotatable disc (36) is positioned at an aperture plane after the dispersive means (31), although this is not essential if the rotatable disc has its outer periphery shaped to provide a cam surface engaged by a cam follower. There is also provided a method of spectral discrimination in a scanning optical microscope, comprising dispersing the light and passing the light through frequency selective means in which the form of rotating discs controls the frequency of transmitted light.

Abstract: The invention relates to a method of determining mainly the compressibility number K, the standard volumetric gross calorific value Hv,n and the standard density ρn of test gases using values determined from a spectrum of the test gases. The invention describes various approaches of translating the values for determining the desired values using the data of the spectrum in the operational condition to the standard reference condition using two-step iteration processes without having to subject the test gases to time-consuming treatments. The invention further relates to devices for determining the values required for the methods and which further develop devices for carrying out the methods.

Abstract: A holographic grating spectrophotometer for detecting ozone and sulphur dioxide in the atmosphere is described which provides automatic calibration and which provides automatic linearity correction for the photomultiplier tube. Automatic calibration is provided by using a computer to control a stepper motor to move the grating so that the photomultiplier tube receives maximum intensity at the calibration wavelength of 302.1 nm from a mercury source. Automatic linearity correction is obtained by cycling a wavelength selection mask across exit slits located in the focal plane of the device and firstly combines separately taken counts of two different wavelengths and comparing this sum with the sum of counts of these wavelengths taken simultaneously. The difference is used to calculate photomultiplier tube deadtime and improve accuracy of the results. In a preferred embodiment five wavelengths are used to calculate ozone and sulphur dioxide levels, and a stepper motor driving a cylindrical wavelength selection mask permits exit slits to be exposed to predetermined wavelengths one at a time.
