Optical systems and optoelectronics – future sensors and displays

“Optical technologies will change the way we live”

Dr. Reinhold Fiess, Senior Expert

I completed my studies and PhD in the field of electrical engineering with a specialization in optoelectronics. Within the corporate research department at Bosch, I am currently working as a senior expert for optical systems. Having acquired experience during different assignments ranging from research to production, I now contribute to a multitude of activities concerning the research and development of optical sensors and displays, such as micromechanical laser displays, holographic 3D displays, and novel optical components. The application perspectives of these technologies are given by future automotive and mobile displays or sensor systems for automated driving.

What are the biggest scientific challenges in your field of research?

The developed systems must be miniaturizable, easy to use, and have the potential for low cost, and this, of course, at high quality. In particular, when used in motor vehicles, the systems must work under very severe environmental conditions, for example in a temperature range of -40 to 100 °C.

How do the results of your research become part of solutions "Invented for life"?

For example, prototypes are created on which feasibility studies are carried out. Work in the team is very important, and this is where the research findings are discussed. In some cases, it takes a long time to achieve reliable solutions, so patience and perseverance are also fundamental in applied research. My current area of research on displays has the particular charm that we can visualize our results in the early stages and thus evaluate them for their potential use.
