Abstract
An apparatus of structured light generation is equipped with a light source and a lens unit. The lens unit is installed in a compact housing of the apparatus of structured light generation. Moreover, the lens unit constructed two different optical path lengths within the housing. By the lens unit, light beams from the light source are collimated and converted into linear light beams. The linear light beams are locally overlapped or globally overlapped. Consequently, the light beam from the light source is shaped into a linear structured light or a linearly-overlapped structured light for detection.
Claims15
An apparatus of structured light generation, comprising:
- a light source emitting a light beam;
- a lens unit converting the light beam into a linear light beam, wherein the lens unit comprises a lens element with a first surface and a second surface, wherein the first surface and the second surface are opposed to each other, the first surface faces the light source, the first surface has a radius larger than 0.189 mm or has a diffracting function, and the first surface of the lens element is a free-form surface and a lenticular lens array structure is formed on the second surface of the lens element;
- and
- a housing accommodating the light source 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 light beam, wherein the first optical path length and the second optical path length are different.
