Abstract

We have developed a smallest optics for a Vertical shaped Ultra short throw Projector which can project a Full HD (1920 × 1080 pixels) image. In order to realize the smallest optics, we have designed three specific optical parts. First, we have designed a negative distortion lens to minimize each optical parts. Second, we have put a flat mirror to bend optical paths. Finally, we have designed a freeform mirror to correct the distortion of a projected image. By using these parts, we have realized the smallest optics and excellent image quality for the Vertical shaped Ultra short throw Projector.
