1. An image processing apparatus comprising:
- a laser unit;
a collimating lens that converts a laser beam emitted from the laser unit into a collimated beam;
a phase modulation array that modulates a phase of the collimated beam to generate a holographic image; and
a positioning block,wherein the laser unit is positioned at and secured to the positioning block,wherein the positioning block has an optical path that allows the laser beam emitted from the laser unit to pass therethrough, andwherein a position of the collimating lens in an optical axis direction is adjusted and the collimating lens is secured in the optical path.

Abstract
A reddish collimated beam and a greenish collimated beam respectively emitted from one and another light emitters are separately radiated to different conversion regions of a phase modulation array. In the phase modulation array, phases of components of light are converted through a plurality of pixels, thereby obtaining a modulated beam that is an interfered beam. An image of the modulated beam is formed on a screen to generate a holographic image. The one light emitter and the other light emitter are each configured as a separate block, stacked one on top of another on a reference base, and separately positioned and secured.
