Abstract

An emitting device (26) for a scanning optical detection system of a vehicle for monitoring at least one monitoring region (14) for objects is described, having at least one light source (40a, 40b) for generating at least one optical emission signal (32a, 32b) and having at least one diffraction unit (50a, 50b), which has a diffractive effect on the at least one emission signal (32a, 32b), for controlling at least one beam direction (66a, 66b) of the at least one emission signal (32a, 32b). At least one diffraction unit (50a, 50b) which is settable to set the beam directions (66a, 66b) associated with the respective signal paths (41a, 41b), is arranged in at least two different signal paths (41a, 41b) of one emission signal or various emission signals (32a, 32b). At least one beam alignment unit (38) is arranged in the respective signal paths (41a, 41b) after the at least one diffraction unit (50a, 50b) to align the set beam directions (66a, 66b) in the at least one monitoring region (14) while maintaining at least one angle offset between the set beam directions (66a, 66b) generated before the at least one beam alignment unit (38) or to generate at least one angle offset between t…
