Abstract
A holographic imaging device includes a laser device, a laser beam expanding and collimating system and a liquid crystal cell. The laser beam expanding and collimating system is configured to expand a light beam from the laser device and enable the expanded light beam to be transmitted substantially vertically to the liquid crystal cell. An amplitude-transmission coefficient distribution of the liquid crystal cell is determined in accordance with a brightness distribution of holographic interference fringes of an object to be displayed.
