Beschreibung
Zusammenfassung:	Disclosed herein is a printing apparatus using an order-separation type optical modulator. The printing apparatus includes an illumination lens system, a diffraction type optical modulator, a filter system, and a projection system. The illumination lens system converts light, which is output from a light source, into linear light and outputs linear, parallel light, the diffraction type optical modulator performs desired modulation on the linear, parallel light emitted from the illumination lens system and forms diffracted light having a plurality of diffraction orders.
