レーザ光源プロジ工クタ向け高輝度・超短焦点投写光学系および色再現処理技術の開発

摘要

Our newly developed ultra-short throw distance laser light source projector is composed of triple rod illumination optics, mirror-lens hybrid ultra-wide angle projection optics and laser color processing. This projector has achieved the highest brightness of 7,0001m, the shortest throw distance of 60 cm at 100-inch image size and wider color gamut of 190% compared with sRGB by making full use of the advantages of laser such as high lumi­nance, small etendue and high color purity. These specifications improve the visibility, convenience of installation and vividness of the image. In this paper, we describe our original developed technology such as the triple-rod illu­mination optical system, ultra-short projection optical system and laser color processing.%1．まえがきプロジュクタ（以後PJ）は，その設置自由度の高さや大画面化の容易性から，表示装置としてディジタルサイネージ，イベント，シネマなどさまざまな用途で用いられている．これらの用途において，以下の三つの性能に対する要望が高い．
