摘要
The projector (1) is provided with a projection grating (3) so that a strip pattern can be projected onto the test object (6). A camera registers the latter with the superimposed Moire pattern, a reference grating (4) extending in parallel with the projection grating in the observation path. A sliding arrangement is used to move and measure the shift path of a calibrating device w.r.t. the test object at right angles to the gratings' plane.A control and evaluating computer controls the sliding arrangement as well as registering and evaluating the measurement data. A CCD sensor and optics can be used for equalising the grating constants.
