Abstract: A hologram is synthesized by moving two apparent sources of diverging wave energy distributions to form different interference patterns and by superimposing these interference patterns on a recording surface. The source or apex of one diverging wave energy distribution is moved substantially in a plane. The source or apex of the other diverging distribution is moved substantially perpendicular to the recording surface by directing a thin beam of laser light to strike a blazed grating disposed substantially perpendicular to the recording surface. The grating expands the received laser beam to form a diverging wave energy distribution. The apex of this distribution is moved by deflecting the laser beam to strike different positions on the grating at different distances from the recording surface.
