1. A projection apparatus comprising:

  • an optical device configured to be capable of diffusing coherent light beams;

    an irradiation unit configured to irradiate coherent light beams to the optical device so that the coherent light beams scan the optical device;

    a light modulator configured to generate a modulated image using coherent light beams incident on and diffused at respective points of the optical device from the irradiation unit; and

    a projection optical system configured to project a modulated image generated by the light modulator onto a scattering plane,wherein the light modulator comprises;

    a plurality of micromirrors provided for each pixel, configured to switch a reflection angle of each coherent light beam from the optical device; and

    a reflection angle controller configured to control a timing of switching a reflection angle of each of the plurality of micromirrors so that the timing becomes irregular for each frame period that is a time unit for generating the modulated image.
