DOE 可以实现对光束的整形,产生平顶光束或者特定形状的光斑。在DOE 在消费电子中的细分应用场景是 AR和VR设备、智能终端设备中,用于生成紧凑的光学系统,提供高质量的图像和增强的视觉体验,以及光学性能。
There are two main families of DOE products: beam splitters and beam shapers.
Optical beam splitter DOEs are used to split a single laser beam into several beams, each of these has the same char-acteristics as the original beam – except for the power and the angle of propagation.
Beam shaper DOEs are used to transform a near-Gaussian incident laser beam into a uniform-intensity spot of either round, rectangular, square, line, or other shape with sharp edges in a specific work plane.
