A stereo camera includes a first lens and a second lens, a first light shield unit and a second light shield unit respectively provided at front sides of the first and second lenses to shield light incident on the first and second lenses, a first fan and a second fan respectively provided at the sides of the first and second lenses to defrost a windshield of a vehicle, and a front case in which the first and second light shield units are provided at both sides of a main body. The first and second light shield units are attachable to or detachable from the front case, a width of the first light shield unit is less than a length thereof and is greater than a height thereof, and a distance between the first and second lenses is greater than the width of the first light shield unit.

Light emitting unit, in particular of or for a triangulation-based distance measuring device, for providing defined measuring light, in particular laser light, is disclosed. The light emitting unit comprising a light source for emitting light, in particular a laser light source for emitting laser light, and a beam forming assembly for shaping the light by affecting propagation of the light emitted by the light source, wherein the beam forming assembly is arranged and designed so that measuring light is provided in form of a light line having a midpoint and two opposite ends. The beam forming assembly comprises at least one micro-lens array, the at least one micro-lens array comprises a plurality of micro-lenses, wherein the micro-lenses are designed and arranged in joint manner next to each other with algebraic signs for curvatures of successive micro-lenses being opposite and so that a periodic structure is provided.
