Abstract
A laser beam generating device is provided for generating multiple mutually orthogonal light beams. The device includes a laser light generator that generates at least three output beams. A beamsplitter of the laser light generator has two incident surfaces orientated at forty-five degrees in relation to an optical axis. A first portion of a light from a light source is incident on a first of the two incident surfaces and output as a first output beam in a first direction orthogonal to the optical axis. A second portion of the light is incident on a second of the two incident surfaces and output as a second output beam in a second direction opposite the first direction. The light source is arranged in relation to the beamsplitter such that a third portion of the light bypasses the beamsplitter and forms a third output beam projected parallel to the optical axis.
