Abstract
The invention describes a laser device (10) comprising an array (50) of laser emitters (100) and a control unit (200), the array (50) comprises at least a first sub array (110) of laser emitters and a second sub array (120) of laser emitters, wherein the first sub array (110) emits laser light of a first polarization and the second sub array (120) emits laser light of a second polarization being different from the first polarization, and wherein the control unit (200) is adapted to control the first sub array (110) and the second sub array (120) such that the polarization of the laser light emitted by the array (50) can be changed. The invention further describes a sensor device (300) and an optical detection system (400) comprising such a laser device (10). Furthermore, a method of determining the shape of an object by means of the optical detection system (400) is described.
