In a method of imaging an object, for dental purposes, comprises: a)
projecting a striped pattern on to the object to be imaged, b) recording
the projected striped pattern as a basic image (R.sub.i) with a camera,
steps a) and b) being carried out at a number of different positions of
the phase relationship of the striped pattern, and c) computing an image
of the object from the plurality of mutually out-of-phrase basic camera
images. Provision is made for suppression of periodic disturbances in
that, in step c), c.sub.1) at least two groups of basic images (R.sub.1,
R.sub.2, . . . , R.sub.n; R.sub.2, R.sub.3, . . . , R.sub.n+1) are formed
from the basic camera images (R.sub.1, . . . , R.sub.m), c.sub.2) a phase
related image (Pj) of the object to be imaged (20) is computed from each
group of basic images (R.sub.1, R.sub.2, . . . , R.sub.n; R.sub.2,
R.sub.3, . . . , R.sub.n+1), c.sub.3) the computed phase related images
(P.sub.1, P.sub.2) are averaged such that a phase related image (P)
having a reduced amount of noise is formed, and that c.sub.4) an image of
the object is computed from the phase related image (P) having a reduced
amount of noise.
