Automatic Test System accelerometer

Specimen surface roughness is a linear relationship. 9 angular distribution of scattered light method is to use the method of scattered light intensity and its distribution to measure the surface roughness parameters] a laser beam projected onto the sample surface,ugg milano, its specular direction of the reflected light and scattered light distribution of ten hemispherical , the hemispherical intensity of each point of difference. The time when the surface is very smooth. Intensity mainly in the mirror direction. The rougher the surface, specular reflection direction of the weaker the light intensity, the other points, the stronger the scattering of light. When the light detector receives the light intensity and distribution, through statistics and spectral analysis, or after the anti-scattering of light, can be measured on the surface roughness parameters - such as the spatial wavelength, average slope, average height and arithmetic the average deviation. 10x X-ray diffuse scattering method grab-ray scattering is a newly developed instrument, used in the laboratory. High surface area available for real-time scanning. The basic theoretical model of perfect,tory burch, non-contact measurement. Details of the optical constants do not depend to clams out of the question 0.05mm ~ 5nm roughness parameters. Sub-nanometer to tens of microns in length and 2 to 2.95 correlation between the fractal dimension information. Figure 13 shows the use of x-ray scattering measurement grab the schematic]. Figure l3x-ray diffuse scattering to measure the reflective mirror to scan the angle of incidence twice the speed of scanning the scattering angle. Grab the method by measuring scattering, the specimen is scanned in the incident beam and the beam out of the ambiguous points of the question. Scattering angle fixed at a smaller value of 1. . Can also be repeated in different scattering angles. According to grab a single scattering of ten scans can obtain roughness parameters. Adopt mixed area of about 5mm × 8mm. The surface roughness of the optical measurement techniques, in addition to using laser diffraction. Scattering, such as speckle and polarization measurement instruments that produce interference. Orange light interferometric techniques have also been developing rapidly. And optical technology has its unique advantages. If the area can provide information on surface topography. Non-contact measurement, measuring efficiency, fast response, enabling online measurement. Measurement is now into the nano era, in the semiconductor masks, disks. Space optical lenses. Ring laser gyroscopes, have been proposed RMS surface roughness less than 1nm very smooth surface requirements. Surface roughness to achieve fast, accurate, online and automated measurement. Is still the direction of future development. References 1WbJtehouseDJ. Compa ~ sonbetween ~ y [ussndopticalmethodsforroeasu ~ ngsurfmAnnalsoftheCIRP, 1988.97 (2): 649 ~ 6532VcrburgerTV.
