Traditional displacement measuring device such as roundness measuring equipment, beat appearance etc., its probe normally adopts the contact position to claim sensor, under certain test pressure, the measured workpiece surface is measured.But receive various condition restriction; Do not allow contact damage like working surface; Perhaps to soft, hard brittle material and special geometric shape surface (like interrupted surface, surface that radius-of-curvature is little etc.), superelevation precision surface (like semiconductor membrane, precision optics part); This moment, traditional tangent displacement sensor can't satisfy test request, also just can't obtain measurement data accurately.
With tradition object displacement measurement mechanism to be measured is example, and traditional object displacement measurement mechanism to be measured can be regarded as a kind of profile tester.During test, to guarantee that earlier high precision contact probe contacts with the effective of subject surface to be measured, is evenly rotated by the tested object to be measured of motor-driven, simultaneously image data again.Because the interval separate slot width of its measured surface of object to be measured after the groove milling also is unlikely to have influence on passing through of probe at 0.2-0.5mm.When the characteristic of obviously decline and rising appears in the detected displacement signal of popping one's head in, determine invalid notch data through software processes and also reject, just can draw the valid data of object outline to be measured then.But to not milling the object to be measured of groove, it is just powerless to change the touch probe.Testing tool adopts tangent displacement sensor basically between sheet commonly used both at home and abroad at present.
