  • LOW-SPECKLE LASER LINE GENERATOR
    Publication number: 20240111171
    Abstract: A laser line generating assembly for projecting a low-speckle laser line is provided. The laser line generating includes a laser source, a beam divider and a sub-beam converter. The laser source generating a laser beam having a temporal coherence. The beam divider divides the laser beam into incoherent multiple sub-beams propagating in a same propagation plane. The sub-beam converter generates a plurality of laser light sheets, each laser light sheet being associated with a corresponding one of the sub-beams. Each laser light sheet extends within the propagation plane. The laser light sheets intersect a projection plane to define laser line elements overlapping at least partially to form said low-speckle laser line, the laser line elements having respective speckle patterns which are at least partially uncorrelated.
