Abstract
The use of a diffractive optical element (DOE) in the optical scheme of a laser illuminator of a shooting simulator exposing the target is studied. It is proposed to use the DOE in the optical projection system to form a laser beam with a special intensity profile. The use of the DOE with binary amplitude transmission allows simplification of the manufacture of this block with simultaneous improvement of its performance. The DOE is used as a diffraction attenuator of laser radiation with a period of 2.5 µm and a minimum bandwidth of about 0.8 µm. Results of an experimental study of the laser radiation distribution generated using the DOE and its comparison with distribution of radiation obtained in the usual way are presented.
