Fourier Transform Spectroscopy Method-Fundamental Principle, Recent Developments and Applications
Abstract：Fourier Transform Spectroscopy is now one of the most important and useful spectral methods in infrared and far infrared region. We illustrate here simply the fundamental principle and the intrinsic advantage, review and discuss its recent developments and essential applications in solid state physics, organic chemistry, biological macromolecule, astronomical observation and energy exploitation.- 74

Wall-Stabilized Argon arc UV-VUV Sources
Abstract：Three kinds of wall-stabilized argon arcs satisfactory for different requirement have been developed. The measurement in UV and VUV range indicated that the stability, both short term and long term, and the reproducibility of the spectral radiance of 2.5kW arc and 10kW arc were better than ?0.3%,and the similarity among arcs with the same structure was better than ?1%. The stability and the reproducibility of 1kW arc were better than ?0.8%. This paper discusses the property of the spectral radiance distribution of argon arcs in 165-350nm range, the temperature and electron density diagnostics of argon arc plasma, and the black body limited lines technique for absolute calibration.- 43

A High Throughput Toroidal Grating Monochrornator and VUV Beamline for Synchrotron Radiation
Abstract：A grating monochromator combined by a cylindrical mirror and a straight groove toroidal grating is discussed. The cylindrical mirror is enployed to form the monochromator system of astigmatic coma-free. The monochromator has a large horizontal collection angle. The calculated results show that the line broadering mainly comes from defocusing of the toroidal grating. The expected performance of the monochromator could be obtained. The optical designing process of the monochromator and the VUV beamline confiquration for synchrotron radiation are also considered in detail.- 51

Resolving Power and Wavelength Accuracy of a Seya-Namioka VUV Monochromator
Abstract：This paper analyses in detail the optical parameters of Seya-Namioka system and its bearings on defocusing, which has provided the basis for determining optimum optical parameters. Factors influencing line image quality and wavelength accuracy are investigated and the method of compensating for wavelength errors is discussed.- 36

About ICO-13 Congress and Tsukuba Meeting
Abstract：Author attended the 13th Congress of the International Commission for Optics(ICO-13) held on August 20-24,1984 in Sapporo, Japan and Post Congress Meeting on August 27-28 in Tsukuba. In this review, the general case of the two congresses is introduced. Since author’s interest is in information optics,the emphasis of the paper is on optical computing (in particular, optical computer), effect of laser speckles, image processing and holography, etc.. At the same time, present and future, development of optical techniques in industries in some main developed countries(for example, USA, Japan) is dealt with.- 56

Penning Discharge VUV Source
Abstract：A Penning discharge source working at the discharge current 50 mA—400mA and pressure 10-4 Torr-10-1 Torr has been developed to mainly use in the extreme UV spectra region between 10nm and 30nm. The source can produces a number of intense lines of various gases and cathode materials. When the discharge current reaches 150mA, the high stage ion lines,such as Al Ⅳ 16.01nm, 16.17nm and AlⅢ 16.95nm, 17.04nm, 17.18nm, 17.3nm, 17.56nm can be observed.- 42
