Polymer-based diffractive optical elements for rear end automotive applications
Design and fabrication process
Abstract
Advances in illumination technology in the automotive industry are heading toward the use of coherent sources for adaptable and high-resolution head lamps as well as interior and rear-end lights. We present a cost-effective method to fabricate and design laser-based lighting systems for the rear end in automobiles and other vehicles. The design relies on using binary gratings to generate a desired intensity distribution. For cost-effective fabrication, an optical maskless UV lithography system that employs a spatial light modulator (SLM) for projection of the desired structure onto photoresist is introduced. To replicate the structures onto polymers like poly(methyl methacrylate) (PMMA), we use polydimethylsiloxane soft stamps and a hot embossing system. The experimental results show that the proposed design and fabrication process is promising for high-resolution rear-end lights that might be employed to project symbols or information to guide road users in future.
