One type of hologram scanner driven by power consists of 1. one hologram scanner disk with multiple surfaces 2. one driving device for rotating the hologram scanner disk 3. one laser light device for generating a laser beam which is incidenton the hologram scanner disk with angel theta_i and generating adiffraction beam with angel theta_d 4. one first-order reflecting mirror on which the diffraction beam withangel theta_d is incident and generating a first-order scanning curve 5. one second-order reflecting mirror on which the first-order scanningcurve is reflecting and generating a second-order scanning curve whichis reflecting through the second reflection mirror, then incident on onesurface of the hologram scanner disk with angle theta_ii and diffractinginto one scanning line with angle theta_dd in which theta_ii = theta_i and theta_dd = theta_d
Optical device capable of switching output intensity of light of predetermined polarized wave, optical transmitter using the device, network using the transmitter, and method of driving optical device
