Claim One:
1. A method of imaging an object for dental purposes, comprising the steps of: a) projecting a striped pattern on to the object to be imaged, b) recording the projected striped pattern as a basic image (R i ) with a picture receiver at an angle other than the angle of projection, steps a) and b) being carried out at a number of different positions of the phase relation of the striped pattern, and c) computing an image of said object from the plurality of basic camera images that are out-of-phase with each other (R 1..., R n ), wherein in order to suppress periodic disturbances, i.e., noise, in step c), c1) forming from the basic camera (R 1..., R m ) images at least two groups of basic images (R 1, R 2,..., R n ; R 2, and R 3,..., R n &plus;1), c2) computing a phase related image (P j ) of the object to be imaged from each group of basic images (R 1, R 2,..., R n ; R 2, R 3,..., R n &plus;1) c3) averaging the computed phase related images (P 1, P 2 ) such that a phase related image (P) having a reduced amount of noise is formed, and c4) computing an image of the object to be imaged from the phase related image (P) having a reduced amount of noise.
