Abstract

The present invention relates to an optoelectronic device (100) for determining relative movements or relative positions of two objects, comprising a first object (10) fixed relative to a frame (1) of the device; a second object (20) mounted in spaced relation to the first object (10) and adapted for movement relative thereto; and a plurality of measuring cells for determining movement or displacement of the second object (20) relative to the first object (10). Each measuring cell comprises a light- emitting element (13) and a detector (23) for detecting light from the light-emitting element (13). The invention provides a light shield (30) for the optoelectronic device (100), the light shield comprising a plurality of channels (31) which together define a non-planar or three-dimensional array of light beam paths between the first and second objects (10, 20) of the optoelectronic device. Each channel (31) forms a path for a light beam between a light-emitting element (13) and a detector (23) of the optoelectronic device, and at least two of said channels (31) define light paths which converge with one another from the light-emitting elements (13).
