Presentation of the possibilities of visualizing objects in space through holography, and exploring geometric curves and surfaces with laser beams and computers. Holography as a generalization of perspective imaging. Background, holography instruments, applications of laser beams in perspective and silhouette, geometric background of laser wave interference (computer simulation), construction of hologram with the instruments available in the laboratory and plate appearance. Rotational surfaces – determination of special interest curves with laser devices, wave guides, reflective surfaces of second and higher degree, study of caustic curves and other geometric properties with laser and computer.
