FIELD: electricity.
SUBSTANCE: invention relates to a laser device with controlled polarisation. Laser device (10) comprises array (50) of laser emitters (100) and control unit (200). Array (50) comprises at least first sub-array (110) of laser emitters and second sub-array (120) of laser emitters. First sub-array (110) emits laser light of first polarisation and second sub-array (120) emits laser light of second polarisation (122). Control unit (200) is adapted to control first sub-array (110) and second sub-array (120) such that the polarisation of the laser light emitted by array (50) can be changed.
EFFECT: invention makes it possible to increase the efficiency of determining the three-dimensional shape of objects.
