Abstract

PURPOSE: To allow measurement of high SN ratio simultaneously with a simple device, by measuring a distance at each place in where two displacement guages are arranged in parallel with short pitch and a slide is moved over a whole length of one pitch.
CONSTITUTION: Two displacement guages 6, 7 are arranged in parallel to a linear guide on a slide being linked the linear guide with short pitch. First a saddle 4 is put of solid line and a distance between the displacement guages 6, 7 and an object to be measured is obtained. Then, the saddle 4 is moved one pitch to left side and the distance is obtained at places of two points dotted line with the same way. With this way, the measurement is carried out over the whole length of the object, and the output at each place is converted by A/D converter and the arithmetic treatment is made by computer. By so doing, with once slide movement, it enables to measure simultaneously the linearities of the liner guide and of the object to be measured with high SN ratio.
