Abstract
A positioning system for detection and determination of a relative position between a first unit (1) arranged in a first plane and a second unit (2) arranged in a second plane parallel to said first plane and spaced therefrom. The units (1, 2) are mutually movable parallel to said planes, and the first unit (1) has a radiation source (3) for transmitting a beam of rays (S1) directed against the second unit (2), and a radiation detector (4) for detecting a beam of rays (S2) retransmitted from said second unit (2). The second unit (2) has a passive means (7) adapted, when said relative position lies within specific limits, to receive the beam of rays (S1) transmitted from said radiation source and to retransmit (S2) the radiation received towards said radiation detector (4). The system is characterized in that said passive means (7) has a separate radiation receiving portion (5) which is extended in said second plane and within which the transmitted beam of rays (S1) impinges when said relative position lies within said limits, and a separate radiation retransmitting portion (6) which is in optical communication with and, as seen in a direction parallel to said second plane, is spaced a distance (A) from said radiation receiving portion (5). The radiation detector (4) has a two-dimensionally position sensitive detection area, the beam of rays (S2) retransmitted from said radiation retransmitting portion having a convergence such that it impinges on a limited part (P) of the detection area, said radiation detector being further arranged such that it provides the position information which contains information about where (P) the retransmitted beam of rays (S2) impinges in the detection area.
