摘要:
A method for capturing the image of a target object (Z) illuminated by an illumination laser (1) includes the following steps: a) Illuminating the target object (Z) by means of a pulsed laser beam (L) emitted by the illumination laser (1), which beam is aimed at the target object (Z) in the form of an illumination (L 2 ) beam by an illumination optics unit (2); b) Receiving the illumination beam laser light reflected from the target object (Z) by means of a receiving optics unit (3); c) Directing the received reflected illumination beam laser light to an image capturing device (4) to generate an image of the target object on the image capturing device (4); d) Detecting the angular offset of the image of the target object with respect to a reference axis of the receiving optics unit (3); e) Stabilising the visual axis of the image capturing device (4) detected by imaging of the target object device by means of a first optical correcting element (30) of the receiving optics unit (3) that compensates for the angular offset; wherein the following additional steps are carried out to stabilise the imaging of the target object: a' 1 ) Decoupling a partial beam (L 1 ) from the laser beam (L) emitted by the illumination laser (1); a' 2 ) Delaying the decoupled partial beam (L 1 ) in an optical delay device (62); a' 3 ) Illuminating the target object (Z) by means of the partial beam (L 1 ) that is directed at the target object (Z) by the receiving optics unit (3); b' 1 ) Receiving the partial beam laser light which is reflected by the target object (Z) and which defines a reference wavefront by the receiving optics unit (3); b' 2 ) Decoupling the received reflected partial beam laser light from the light that is received by the receiving optics unit (3); c') Directing the decoupled reflected partial beam laser light to a wavefront sensor (50); d') Detecting a wavefront error in the received reflected partial beam laser light, and e') Fine tuning th
