Abstract / Hauptanspruch
An optical pattern projector used for projecting a structured-light pattern onto an object for dimensioning is presented. The optical pattern projector utilizes a laser array, a lenslet array, a lens, and a diffractive optical element to create a repeated pattern of projected dots. The pattern repetition is based on the grid pattern of laser array. Each laser's collimated beam, when projected through the lens, impinges on the diffractive optical element from a slightly different direction. The diffractive optical element creates a sub-patterns that continue propagating along these different directions and combine on a target to produce a repeating optical pattern.
