    • The invention relates to a light modulator for representing complex-valued data, comprising an encoding area that has an arrangement of pixels, the phase of which can be controlled. The aim of the invention is to largely avoid an interfering optical path difference between adjacent pixels or pixel groups when a complex value is encoded in several adjacent phase pixels of the encoding area, said optical path difference varying according to the angle. Said aim is achieved by associating one respective specific structured delaying layer which causes the optical path of an incident linearly polarized beam to change according to the angle, with at least one predefined pixel of a group of adjacent pixels of the encoding area (2). The thickness (d) of said delaying layer is designed such that the modification of the optical path caused by the delaying layer runs in the opposite direction from the angle-related modification of the optical path difference between individual pixels of the pixel group and at least partly or fully compensates the angle-related modification of the optical path difference.
    • 本发明涉及一种用于表示复值数据的光调制器,包括具有像素排列的编码区域,其相位可被控制。 本发明的目的是在复数值被编码在编码区域的几个相邻相位像素中时,大大地避免相邻像素或像素组之间的干涉光程差,所述光程差根据角度而变化。 所述目的是通过将一个相应的特定结构延迟层与使得入射线性偏振光束的光路根据角度而与编码区域(2)中的一组相邻像素的至少一个预定义像素相关联来实现的。 所述延迟层的厚度(d)被设计成使得由延迟层引起的光路的修改在与像素组的各个像素之间的光程差的角度相关的修改方向相反的方向上延伸,并且至少 部分或完全补偿光程差的角度相关修改。
