Claim Text:
1. A structured light generation device, comprising: a laser diode emitting an invisible laser spot; a lens unit converting the invisible laser spot into a linear laser beam; and a housing accommodating the laser diode and the lens unit, wherein within the housing, the lens unit constructs a first optical path length and a second optical path length for the invisible laser spot, and the first optical path length and the second optical path length are different, wherein the lens unit comprises a lens element, wherein a radius of a first surface of the lens element is larger than 0.189 mm, wherein the first surface faces the laser diode and is an aspheric surface, or a first surface of the lens unit with a diffracting function faces to the laser diode and is a planar surface.
