Method for configuring sensors

The invention relates to a device for locating objects penetrating into a region of space to be monitored, having a housing (1) which contains a transmitter (3) and a receiver (4) for optical radiation as well as a rotatable optical deflecting device (8) with, on the one hand, a transmitting deflecting mirror (11), which can be rotated about a rotation axis (10) and is inclined with respect to the latter for a beam (5) emerging through a window (2) in the housing (1) into the region of space to be swept by the emerging beam (5) and, on the other hand, with a receiving deflecting mirror (12) for directing a beam (16), reflected from the region of space and incident through the window (2), to the receiver (4). The window (2) is constructed in the form of a spherical section (18) whose centre is the point of intersection of the rotation axis (10) with the optical axes of the incident and emerging beams (5, 16), the transmitting deflecting mirror (11) and the receiving deflecting mirror (12) perpendicular thereto being arranged at an angle of 45.degree. to the rotation axis (10).
