More Information
Summary:The invention describes a laser arrangement (100) comprising a Laser array (110) and an optical structure (140) for providing a defined illumination pattern in a defined field-of-view, wherein the optical structure (140) comprises a diffuser (144) arranged to change a distribution of laser light (10) emitted by Lasers (130) comprised by the Laser array (110), wherein each Laser (130) is characterized by an emission cone, wherein the optical structure (140) is arranged to transform the laser light (10) to transformed laser light (150) such that an overlap of laser light (10) comprised by the emission cones of at least a group of the Lasers (130) is increased in the field-of-view in comparison to a diffuser which is arranged to diffuse perfectly collimated laser light to a flat-top intensity profile in the field-of-view.The invention further describes a lighting device comprising such a laser arrangement (100), a time-of-flight camera (200) comprising such a lighting device and a method of manufacturing the laser arrangement (100).
