Making news: automotive lighting

Stefan Hadrath, Peter Brick

Speakers from a number of companies and research institutes provided the most recent advances in optical design and novel sources for the automotive industry. Among the speakers in a session on the topic in the Illumination Optics conference were Andreas Timinger from Philips Technologie GmbH and Stefan Hadrath from Osram GmbH (above at right with session chair Peter Brick of Osram GmbH).

Timinger's topic (9629-14) was "Current trends in automotive front lighting lamps: an optics designer's view." Laser headlights and LED front-lighting in mass-market cars bring automotive lighting to the news pages, he noted. But also beyond the spectacular installations, halogen lamps, Xenon-discharge lamps, and standardized LED-lamps enable interesting new products.

Timinger described how the photometric properties of these light sources can be translated into systems answering the market's needs for styling, cost efficiency and energy efficiency.

In "Optical design of a laser-based headlamp," Hadrath noted that high luminance and thereby large headlight ranges are one of the main targets of current developments in car headlamp designs.

LARP technology (laser-activated remote phosphor), in which blue laser diodes are used to pump a phosphor converter to emit bright presented an optical design of a laser headlight, provides an innovative approach, Hadrath said. He described the use and functionality of multiple single laser diodes and the phosphor conversion and color mixing.

 

Avoiding laser damage

Jin Huang speaks on laser damage

In the conference on Optical Fabrication, Testing and Metrology, Jin Huang from the China Academy of Engineering Physics gave an invited talk on "Characterization and removal of laser damage precursors in fused silica optics" (9628-16), as part of a session on Laser Damage, Defects, and Contaminations.

 

Optics in design and engineering

Among speakers Tuesday in the comprehensive conference on Optical Design and Engineering, Garrett West from NASA Goddard Space Flight Center spoke on "Optical design with freeform surfaces at NASA GSFC" (9626-33).

In a session on Theory and Modelling, Andrea Berner from Carl Zeiss reported on her team's work in "Chromatic variation of aberration: the role of induced aberrations and raytrace direction" (9626-18).

David Hasenauer from Synopsys reported on "The limitations of using M-squared for input beam characterization in simulation software" (9626-15).

Andrew Harvey of the University of Dundee spoke on "Computational Imaging; the improved and the impossible" (9626-21), reporting on his team's work with computational-imaging techniques to enable an increase in the robustness of information transfer.

Computational imaging has been made possible and attractive with the trend for advanced manufacturing of aspheric, asymmetric lens shapes at lower cost and by the exploitation of low-cost, high-performance digital computation, he noted. Continuing these trends will continue to increase the importance of computational imaging.

The first full day of conference activities on Monday got off to a busy start with attendees showing up in large numbers for technical events beginning with the plenary session, where symposium chair Wilhelm Ulrich (Carl Zeiss AG) welcomed the audience to officially begin the conference.

On-stage with Ulrich were posters of optics and photonics luminaries, in observance of the International Year of Light and Light-based Technologies.

SPIE Board of Directors member Julie Bentley, University of Rochester, also welcomed participants and noted that 2015 is SPIE's 60th anniversary.

She presented the SPIE 2014 Rudolf Kingslake Medal and Prize, given annually to an outstanding paper published in Optical Engineering, to authors from Fraunhofer IOF: Stefan Heist, Andreas Mann, Peter Kühmstedt, Peter Schreiber, and Gunther Notni.

Their winning paper, "Array projection of aperiodic sinusoidal fringes for high-speed three-dimensional shape measurement," was published in the November 2014 issue of the journal.

Opening plenary speaker Reinhard Voelker, SUSS MircroOptics SA, gave the capacity audience a fascinating overview of the evolution of micro-optics from 530 million years ago until today.

Voelker said that micro-optics was a key enabling technology in the evolution of early vision systems, through the 17th century. He gave examples in printing in earlier times as well as in present-day photolithography systems that are dependent on micro-optics for their state-of-the-art performance.

The second plenary talk was given by 2015 symposium co-chair Juan Carlos Miñano, Universidad Politécnica de Madrid, in place of Pablo Benítez who unfortunately was injured and could not attend. (Benítez sent his apologies to the audience along with a picture of himself in a cast with his broken leg.)

Miñano spoke on "Freeforms: how many degrees of freedom do they provide." The presentation featured a review of freeform designs, some examples of products where freeform optics are used, and examples of optical design problems where he discussed the minimum number of surfaces prescribed.

In the third plenary talk, Thomas Pertsch of Friedrich-Schiller-Universität Jena spoke on "Diffractive optical elements made from photonic metamaterials," outlining the benefits of including nanotechnology in optical design.

Starting with a review of the history of metamaterials research, he discussed how these principles can be applied to light control by photonic metamaterials.

In particular Pertsch described the advantages and properties of computer-generated holograms from non-dispersive dielectrics. They have successfully demonstrated how to encode different functionality at different wavelengths due to the optical properties.

In looking to the future, he commented that the limit currently is overall efficiency. Pertsch said he expects that improved performance and capability would come with the development of the next generation of photonic metamaterials.

Reiner Garreis of Carl Zeiss SMT GmbH concluded the session with a final plenary talk, on "Optical lithography forever: extending Moore's Law by extending EUV optics." Garreis’ overview of Moore’s Law highlighted recent developments in optics that have enabled continued advances in the semiconductor roadmap.

In particular, he said, the EUV program at Carl Zeiss has led to advances in coatings, optical design, and mechanics resulting in the newest EUV optical system.

 

Thin films past, present, and future

History, recent developments, and the latest applications were covered in the opening session of the conference on Advances in Optical Thin Films chaired by Angus Macleod of the Thin Film Center. Speakers included Norbert Kaiser of Fraunhofer IOF, Helmut Bernitzki of Jenoptik Optical Systems GmbH, and Ulrike Shula of Fraunhofer IOF.
