    • An electrically variable optical filter includes a first optical element including a first angled face and a second optical element including a second angled face. The second angled face is substantially parallel to and spaced apart from the first angled face. At least one separation actuator is affixed between the first optical element and the second optical element and is operable to change a separation distance D between the first angled face and the second angled face. Light waves transmitted through the first optical element are selectively transmitted through to or reflected away from the second optical element as a function of wavelength and the separation distance D.
    • 电可变滤光器包括第一光学元件,其包括第一倾斜面和包括第二倾斜面的第二光学元件。 第二倾斜面基本上平行于第一倾斜面并与其间隔开。 至少一个分离致动器固定在第一光学元件和第二光学元件之间,并且可操作以改变第一倾斜面和第二倾斜面之间的间隔距离D. 透射通过第一光学元件的光波被选择性地透射到第二光学元件或从第二光学元件反射离开,作为波长和分离距离D的函数。
