    • A variable magnification optical system projects an image onto a screen with a sufficient magnification without requiring a large-sized mirror. The variable magnification optical system includes a first optical system through which a light beam modulated with an image signal corresponding to the image is passed; a second optical system disposed downstream of the first optical system in a direction of travel of the light beam along an optical axis; and a reflective optical element having a magnification power that is configured to reflect the light beam from the second optical system toward the screen. A magnification of the image projected on the screen is changed by moving the reflective optical element relative to the object plane, thus changing a distance between the screen and the reflective optical element, while an incident angle of the light beam on the screen is maintained substantially constant.
    • 可变放大倍率光学系统将图像投影到具有足够倍率的屏幕上,而不需要大尺寸的反射镜。 可变放大率光学系统包括第一光学系统,通过该第一光学系统通过与图像相对应的图像信号调制的光束; 第二光学系统,沿着所述光束沿着光轴的行进方向设置在所述第一光学系统的下游; 以及反射光学元件,其具有被配置为将来自第二光学系统的光束反射到屏幕的放大倍率。 通过相对于物体平面移动反射光学元件来改变投射在屏幕上的图像的放大率,从而改变屏幕和反射光学元件之间的距离,同时保持屏幕上的光束的入射角基本上保持 不变。
