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

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

Abstract

AbstractHolograms 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.
