1. A device comprising:

  • a detector,wherein the detector is arranged to detect different polarizations of laser light,wherein the detector comprises a camera chip and a polarization filter;

    an array of laser emitters, the array comprising at least a first sub array of laser emitters and a second sub array of laser emitters; and

    a control circuit,wherein the first sub array emits a first laser light of a first polarization,wherein the second sub array emits a second laser light of a second polarization,wherein the second polarization is different from the first polarization,wherein the control circuit is arranged to change the first polarization and the second polarization,wherein the control circuit is arranged to control the first sub array and/or the second sub array independently,wherein the first laser light is not coherent to the second laser light,wherein the control circuit is arranged to control the coherence of the first laser light and the second laser light.
