A hologram scanner is constructed with a driving source for providing a rotational force, a deflection disk installed at the rotation shaft of the driving source for forming a scanning line, the deflection disk having a plurality of sectors where a hologram pattern for diffracting and deflecting incident light is formed, a TE polarized light emitting device, arranged to face one side of the deflection disk, for emitting TE polarized light so that major axis of an elliptical spot formed at a predetermined position on the deflection disk by the incident light is perpendicular to the radius vector of the deflection disk passing through the spot having an elliptical cross-section and a TE polarization mode, and an optical path altering device for altering the proceeding path of incident light, so that a scanning line formed by the rotation of the deflection disk proceeds to a photoreceptor medium.
