Foreword

This standard is equivalent to using ISO 11562.1996 "Geometrical Product Specifications (GPS) Surface texture Profile method of phase correction filter The metrological characteristics "(in English). This standard is equivalent translation ISO 11562.1996. For ease of use, this standard made the following editorial changes. --- "This International Standard" be replaced by "this standard"; --- Remove the foreword and introduction of international standards; --- The scope of the Standard adds description. "This standard applies to the measurement surface structure characteristics of phase correct filters." This standard replaces GB/T 18777-2002 "Geometrical product specifications (GPS) Surface texture Profile method of phase correct filters The metrological characteristics. " This standard and GB/T main differences 18777-2002 is. --- 2nd chapter written in the format of terms and definitions have been rewritten; --- Appendix B of the text and B. 1 has been rewritten, and the international and domestic standards achieved consistency; --- Added Appendix C, consistent with international standards achieved. The Standard Appendix A, Appendix B is an informative annex. The standard dimensions and geometry by the National Technical Committee of Standardization Technical specifications and centralized. This standard is mainly drafted by. The machine Productivity Promotion Center, Harbin Measuring & Cutting Tool Group Co., Ltd., China Institute of Metrology Study hospital, the Beijing Institute of Metrology. The main drafters of this standard. Wang Xinling, Wang Zhongbin, Lang Yan Mei, high Si Tian, \u200b\u200bWu Xun, Deng Takami. This standard replaces the standards previously issued as follows. --- GB/T 18777-2002.

1 Scope

This standard specifies the metrological characteristics for measuring the surface profile of the phase correction filter. The standard also specifies how to separate special surface profile of the short-wave and long-wave components. This standard applies to the measurement of properties of the surface structure of the phase correction filter.

2 Terms and definitions

The following terms and definitions apply to this standard. 2.1 The separation filter contour growth wave and short-wave components. 2.1.1 No cause asymmetric contour deformation phase shift contour filter. 2.2 Longwave edge components at all points on the weighted average of the adjacent points contour shapes. 2.3 It shows amplitude of the sinusoidal profile with the change in wavelength attenuation characteristics. 2.4 For calculating each point by point adjacent to the center line weighting function is formed on the contour. Note. The transmission characteristics of the center line is the Fourier transform of the weighting function. 2.5 Sinusoidal contours by contour filter amplitude attenuation corresponding to 50% of the wavelength. NOTE. its contour filter cut-off wavelength value to identify. 2.6 When two different cut-off wavelength of the phase correction filter is applied to the contour, more than 50% transmission amplitude sinusoidal contour wavelength Range. Note. The short wavelength cutoff filter contour to retain the long-wave edge components, the contours of the long wavelength cutoff filter Reserved shortwave edge components. 2.7 Given a long-wave transmission cutoff wavelength band and short wave cutoff wavelengths.
