Abstract (en)
[origin: WO2010049038A1] The invention relates to a device (110) for reflecting a beam (LS1, LS2), such as a laser or light beam, having at least one beam source (1, 2) for monitoring a monitoring area for the presence of an object (101, 102), comprising one rotating mirror (10) for each beam source (1, 2), catadioptic reflectors (3, 4, 5), and light sensors (7, 8, 13, 14), wherein the beams (LS1, LS2) reflected back by the reflectors (3, 4, 5) impinge on the light sensors (7, 8, 13, 14) directly via the mirror (10) or via a further beam divider (15) between the mirror (10) and the light sensors (7, 8, 13, 14). The device (110) is characterized by simple retrofitting.
