摘要

全息图作为光学元件已被广泛应用。然而，将它们与像led这样的非相干和发散光源一起使用是很困难的，因为它们的特性需要在制造过程中用激光模拟，以获得所需光分布的正确重建。我们提出了一种新的设置，允许在制造过程中具有高度的灵活性，它能够生产出可以直接用非准直led照明的体全息单元阵列(vca)。给出了反射全息图的结果。

Manufacturing of volume holographic cell arrays for usage with uncollimated LEDs in automotive applications

Abstract Holograms have found their use as optical elements in a variety of applications. Yet using them with incoherent and divergent lightsources like LEDs proves difficult, as their characteristics need to be simulated by lasers during manufacturing to get a correct reconstruction of the desired light distribution. We present a new setup to allow for a high flexibility during the manufacturing process, which is able to produce volume holographic cell arrays (VCAs) that can be illuminated directly with uncollimated LEDs. Results are presented for the case of reflection holograms.
