Abstract

Double-light-path method with an integral sphere is adopted to obtain the reflectivity indirectly at the wavelength λ=1.06μm for extinction dope on different material samples such as curtain, carpet, the surface of concrete components of the chamber. At laser wavelengths in far IR wavebands, such as CO₂ tunable laser with the wavelengths among the range from 9.0μm - 11μm, an improved method is used with a diffuse reflection gold panel with weak absorption and high reflectivity in far IR waveband. By using the blackbody for contrast during test, the sky background for the test environment is utilized. The extinction performance of chamber is checked by sampling different position of the chamber's inner surface. At last, further error analysis, which is intended to reduce the measurement errors in the test procedures and in the test data proceedings, is provided.
