Abstract:
An apparatus for the moiré measurement of an optical test object includes a grating arrangement made of a first grating ( 25,  . . . ) which is positionable in the optical beam path upstream of the test object and a second grating ( 11,  . . . ) which is positionable in the optical beam path downstream of the test object, an evaluation unit having at least one detector ( 12,  . . . ), for evaluating moire structures produced by superposition of the two gratings in a detection plane situated downstream of the second grating in the optical beam path, and at least one aperture stop ( 14,  . . . ), by way of which the light distribution which was produced after the light exit from the second grating can be shadowed in a region-wise fashion such that only light of a subset of all field points on the second grating reaches the detection plane.

Claim (Index 18):
A method for the moir\u00e9 measurement of an optical test object using an apparatus as claimed in  claim 1 , comprising, with the at least one aperture stop, shadowing the light distribution which was produced after the light exits the second grating in a region-wise fashion in a plurality of measurement steps such that in each case only light of a subset of all field points on the second grating reaches the detection plane.
