Abstract: According to an example aspect of the present invention, there is provided an optical scanning module, comprising a scanning mirror, wherein the scanning mirror is arranged to direct a first light signal coming from a single light source to a first telescope objective via a first optical path, and at least one second light signal coming from the single light source to at least one second optical path, to scan at different distances with different angular resolutions, wherein the first optical path is different than the second optical path, and the optical scanning module is arranged to receive a reflected version of the first light signal via the first telescope objective and the first optical path, and a reflected version of the at least one second light signal via the at least one second optical path.
