Abstract
A device for screening interfering radiation from a radiation source from reaching a radiation receiver. The device includes a sensing device determining the position and orientation of the radiation receiver relative to the radiation source; a matrix, positioned in front of the radiation receiver, of elements which can adopt a varying transmittance and which cover the solid angle within which it is desirable to screen interfering radiation; and control equipment which calculates in what position relative to the radiation receiver a radiation obstacle is to be placed to be able to screen the radiation source and which controls the elements of the matrix in such a manner that the matrix forms a partial or complete radiation obstacle in the estimated position.

A device for screening interfering radiation from a radiation source from reaching a radiation receiver, comprising:
- a sensing device determining a position and orientation of the radiation receiver relative to the radiation source;
- a matrix, positioned in front of the radiation receiver, of elements which provide a varying transmittance and which cover a solid angle within which it is desirable to screen interfering radiation;
- and
- control equipment which estimates in what position relative to the radiation receiver a radiation obstacle is to be placed to be able to screen the radiation source and which controls the elements of the matrix in such a manner that the matrix forms at least a partial radiation obstacle in the estimated position.
A device for screening interfering radiation from a radiation source from reaching a radiation receiver, comprising:
- a sensing device determining a position and orientation of the radiation receiver relative to the radiation source;
- a look-through device, positioned in front of the radiation receiver, having elements which provide a varying transmittance and which cover an angle within which it is desirable to screen interfering radiation;
- and
- control equipment which calculates, using an output from said sensing device, in what position relative to the radiation receive a radiation obstacle is to be placed to be able to screen the radiation source and which controls the look-through device in such a manner that said look-through device forms the radiation obstacle in the calculated position.
