Technical stage device and method for determining a correlation function

A technical stage device (1), comprising:

• a fastening element (2),
• a bearing element (3),
• a functional element (4) and
• a transceiver apparatus (8) comprises at least two signal transmitting elements (5) and at least two signal receiving elements (7);
• wherein the functional element (4) is arranged on the bearing element (3) so as to be pivotable about a tilt axis (14) and wherein the bearing element (3) is arranged on the fastening element (2) so as to be rotatable about a pan axis (13),
• wherein a position determination arrangement is provided, which is designed in such a way that a relative movement between the bearing element (3) and the fastening element (2) and between the bearing element (3) and the functional element (4) can be determined,
• wherein the transceiver apparatus (8) is arranged on the bearing element (3) and comprises:
• a first signal transmitting element (5) and an associated first signal receiving element (7) for cooperating with a first signal reflecting element (9) on the fastening element (2) and
• a second signal transmitting element (5) and an associated second signal receiving element (7) for cooperating with a second signal reflecting element (10) on the functional element (4).
