A static multiview display and method employ an array of diffraction gratings to provide a multiview image having a direction that is a function of both color and a propagation angle of a collimated guided light beam. The static multiview display includes a light guide configured to guide light in a longitudinal direction and a light source configured to provide the collimated guided light beam, the propagation angle within the light guide being determined by a longitudinal offset of an optical emitter of the light source. The static multiview display further includes the array of diffractiongratings are configured to scatter out a portion of the collimated guided light beam as a plurality of directional light beams representing the multiview image. 一种静态多视图显示器和方法，其使用衍射光栅阵列来提供具有方向的多视图图像，所述方向是准直的被引导的光束的颜色和传播角的函数。静态多视图显示器包括被配置为沿着纵向方向引导光的光导、和被配置为提供准直的被引导光的光束的光源，光导内的传播角由光源的光学发射器的纵向偏移确定。静态多视图显示器还包括衍射光栅阵列，其被配置为将准直的被引导的光束的部分散射出去作为表示多视图图像的多个定向光束。
