Title: Method of and apparatus for analyzing light
IPC: G01J5/58
Filed: 1975-05-22
Abstract: 1510827 Spectrometric analysis ALLIED CHEMICAL CORP 22 May 1975 [11 June 1974] 22347/75 Heading G1A Apparatus for analyzing scattered light having spectral components regularly spaced in frequency comprises: interferometric means providing a plurality of transmission windows and adjustable so that the frequency spacing of the windows differs from that of the spectral components or from an odd integral submultiple n of the spectral spacing; scanning means for causing the interferometric means to vary the peak transmission frequencies of the windows; means responsive to the transmitted light; and means for calculating the ratio between the intensities of two portions of the light transmitted during respective phases of the scan. A laser 36 directs a narrow coherent monochromatic beam at a gas sample 40 which may be in a remote region in free air, or in a container. The ratio between the aggregate intensities of the Stokes and anti-Stokes spectral lines, produced by rotational Raman scattering on respectively opposite sides of the incident light frequency, is an exponential function of the reciprocal of the absolute temperature of the gas. The scattered light, collimated by a lens 12, is directed through an interferometer 16 (e.g. a Fabry-Perot FPI) wherein the mirror separation is adjusted so that the frequency spacing of adjacent orders or adjacent nth orders of interference differs from the spacing of the Raman lines of a selected molecular species by a predetermined amount, and so that the Rayleigh line at the incident light frequency is blocked by falling between two transmission windows. Modulating means 42 modulates the mirror separation of the FPI in a region between the next adjacent Rayleigh fringes, to produce split fringes having two branches containing the Stokes and anti-Stokes lines respectively, which are transmitted in turn with maximum intensities during different phases of the modulation. Transmitted light 18, directed by a lens 46 through a pinhole 48 on to a photo-multiplier 50, produces a timevarying signal which is separated and processed by a phase-sensitive detector 52 coupled to the modulator 42, to give a signal representing the ratio between the integrated intensities of the Stokes and anti-Stokes lines for application to indicating and recording means 54 (e.g. a CRO and a chart recorder).  The FPI 16 and modulating means 42 also Fig. 3 (not shown) are described in Specification 1436238 with reference to (Fig. 3) of that Specification (Division G1). Modulation is preferably performed over a range not exceeding the spacing between adjacent windows by means of squarewave voltages which cause the modulating means 42 to alternate between conditions of maximum transmission of the most intense Stokes and anti-Stokes lines. The intensity of received light, together with the transit times of the light from the source to the sample and from the sample to the detector, may be measured to determine the position of a remote sample.
