Abstract

The invention relates to a device for projecting structured light in the form of fringes or other patterns using laser sources, which includes an optical head (1) including three consecutive elements mounted on a substrate, i.e. a laser source (10) including VCSELs (9), a collimation diffractive optical element (11) and a light-structuring diffractive optical element (12). The laser source includes at least one VCSEL matrix obtained by combining M bars (14) of N VCSELs in order to obtain (M x N) VCSELs. The diffractive optical elements are phase diffractive optical elements that convert the light emitted by the laser source into a structured light pattern (2). They are made of matrices of (M x N) diffractive optical sub-elements mounted in front of each VCSEL, and are connected to the laser source in order to define an integrated optical head.
