Patent ID: 10965103

Abstract:
A laser arrangement includes a VCSEL array comprising multiple VCSELs arranged on a common semiconductor substrate, an optical structure, and a diffusor structure. The optical structure is arranged to reduce a divergence angle of laser light emitted by each respective VCSEL to a section of the diffusor structure assigned to the respective VCSEL. The diffusor structure is arranged to transform the laser light received from the optical structure to transformed laser light such that a continuous illumination pattern is configured to be provided in a reference plane in a defined field-of-view. The diffusor structure is arranged to increase a size of the illumination pattern in comparison to an untransformed illumination pattern which can be provided without the diffusor structure. The VCSEL array, optical structure, and diffusor structure are arranged such that sections of the diffusor structure do not overlap. Diffusor properties of the diffusor structure vary across the diffusor structure.
