    • A method for translating a spatial light modulator (22) to provide dithering comprises the steps of: providing a support (11) have a high degree of flexibility; rigidly attaching an outer portion (14) of the support to a nonmoving base; attaching an inner web (12) of the support to the outer portion by means of flexible members (16); wherein the support, the outer portion, the inner web, and the flexible members are located in a first plane; wherein the flexible members allows motion of the inner web in only one dimension of the first plane; attaching a piezoelectric device (18) to a first end of the inner web; energizing the piezoelectric device to move the inner web in a positive direction in the one dimension; attaching a spring (20) to a second end of the inner web; and wherein the spring moves the inner web in a negative direction in the one dimension when the piezoelectric device is deactivated.
    • 一种用于平移空间光调制器(22)以提供抖动的方法包括以下步骤:提供具有高度灵活性的支撑件(11); 将支撑件的外部部分(14)刚性地附接到不移动的基部; 通过柔性构件(16)将支撑件的内腹板(12)附接到外部部分; 其中所述支撑件,所述外部部分,所述内部腹板和所述柔性构件位于第一平面中; 其中所述柔性构件允许所述内腹板仅在所述第一平面的一个维度上运动; 将压电装置(18)附接到所述内腹板的第一端; 激励压电装置在一个维度上沿正向移动内腹板; 将弹簧(20)附接到所述内腹板的第二端; 并且其中当所述压电装置被去激活时,所述弹簧在一个维度上沿着负方向移动所述内纤维网。
