principal axis of projectionとは 意味・読み方・使い方

Provided that f: focal length of the projection optical system, h: distance from the optical axis of the projection optical system to an optional point on a surface of the display element, and θ: an angle formed by the optical axis of the projection optical system with a principal ray that has been emitted from the projection optical system to the screen.例文帳に追加

ここで、ｆ：投影光学系の焦点距離、ｈ：投影光学系の光軸から表示素子面の任意の点までの距離、θ：投影光学系の光軸と投射光学系からスクリーンへの出射後の主光線とのなす角とする。 - 特許庁

As for the projection lens 107, an off-axis principal ray from the 3rd lens group is made to cross an optical axis 117 inside the 2nd lens group, and the optical axis of the 1st lens group, the optical axis of the 2nd lens group and the optical axis of the 3rd lens group are aligned with the optical axis 117.例文帳に追加

投写レンズ１０７において、第３レンズ群からの軸外主光線を第２レンズ群の内部で光軸１１７と交わらせ、第1レンズ群の光軸、第２レンズ群の光軸及び第３レンズ群の光軸を光軸１１７に一致させる。 - 特許庁

A principal axis of a cylindrical lens 7 of the projection optical system and a principal axis of an objective 8 of the detection optical system cross each other at a certain angle, and the line CCD 11 detects an intensity distribution of the light rays generated by the illumination rays 7 in the line-like form on a line.例文帳に追加

投光光学系のシリンドリカルレンズ７の主軸と、検出光学系の対物レンズ８の主軸とが一定の角度で交わるとともに、ラインＣＣＤ１１は、ライン状の集光７によって生じる光の当該ライン上における強度分布を検出する。 - 特許庁

A proceeding direction of a principal ray of the light beam L modulated by the light modulation element 12 is not parallel to an optical axis 130 of the projection optical system 13 when the light beam L enters the projection optical system 13.例文帳に追加

光変調素子１２により変調された光Ｌが投射光学系１３に入射するときの、光Ｌの主光線の進行方向が投射光学系１３の光軸１３０と非平行になっている。 - 特許庁
