March, 12th 2019


OCM SpectroNet Collaboration Conference 2019

The addresses recent developments in innovative photonic micro sensors with digital image processing for geo-, color-, multi-, hyper- and full-spectral photonic measurement applications for the optical characterization of materials in industry, biology/medicine, environment and security and in daily life.

09:45 - 17:00h

10 minutes talks by representatives of industry and science

17:00 - 20:00h Get Together with Special Session as well as Pretzels and Beer Special

Optical Spectroscopy vs. Classical Analytics – Comparable Questions and Results?

Each material has its own specific spectral signature independent if it is food, plastics, or minerals.The claim to learn more about these materials and their properties is not new.This also applies to foodstuffs, of course.Besides the analysis of ingredients, we are interested in things like originality and freshness. Of course, these questions are not new and that is why there are traditional and proven analytical methods in food technology.

Together, we will discuss and compare these classical methods and methods of optical spectroscopy with their pros and cons over a glass of beer and pretzels on Tuesday evening.

Our Agenda:

17:00h Welcome at Fraunhofer IOSB
