Patent ID: 7263161

Claim:
An X-ray or neutron optical analysis device for measuring a sample, the device comprising: a radiation source; a radiation detector, said detector having a plurality of substantially identical, separate detector elements disposed parallel to and adjacent to each other in a first x-direction and extending as strips in a second y-direction, orthogonal to said x-direction, to provide one-dimensional spatially resolved detection in said x-direction of radiation reflected, scattered or diffracted by the sample; a detection electronics for processing detector signals from each of said plurality of detector elements, said detection electronics having a maximum radiation intensity per detector element which is reliably processed without overloading; and an optical element disposed upstream of said detector to reduce radiation intensity incident on surfaces of said detector elements, said optical element comprising a filter structured to produce a transmission function f(x) which changes in said x-direction and/or a collimator which is structured for displacement relative to said radiation detector along said y-direction.
