摘要：
The invention relates to a method for measuring the depth of a surface of a test object. According to said method, a colored fringe pattern formed by a sequence of colored fringes (4) is projected onto a surface of the test object, and a fringe pattern (7) reflected by the surface of the test object is detected and evaluated by means of an evaluation device, the colored fringe pattern and the evaluation device being designed such that the depth of the surface of the test object is measured based on the sequence of colored fringes (4) of the reflected fringe pattern (7) and based on a sequence of fringe (5) widths of the reflected fringe pattern (7).
