Headwall Group Presents Twice at the Vision Spectra Conference
The Vision Spectra Conference returns 15 to 17 July 2025, featuring two presentations by Headwall Group companies EVK DI Kerschhaggl and inno-spec GmbH!
Presented by: Matthias Kerschhaggl, EVK
Traditional quality control methods in industries such as food, pharmaceuticals, chemicals, and recycling often still rely on laboratory-based analysis of a limited number of random samples. This approach fails to provide a comprehensive insight about the entire production flow. Quantitative chemical imaging (QCI) offers an impactful solution by enabling real-time analysis of the chemical composition of a material flow directly within the production line.This talk demonstrates the development of an application model using the QCI classification algorithm to quantitatively analyze multiple chemical components, measuring the concentration and distribution of chemical compounds in a product. This paves the way for more efficient and precise quality control in industrial production.

About the presenter
Matthias Kerschhaggl, Ph.D., is CTIO and owner of EVK, an Austrian based expert company for industrial imaging. He is engaged in data science and analytics, predominantly dealing with data streams stemming from sensor-based sorting and control applications used in industries such as food, chemical, mining and pharmaceuticals. He holds a doctorate in experimental physics and has more than 15 years of experience in the fields of statistical learning and data mining of datasets from various areas (astroparticle physics, integral field spectrographs, hyperspectral and inductive imaging).
Presented by: Léa Butruille, Headwall Group
Newly devised hyperspectral UV imaging can be integrated with a camera that operates at longer wavelengths, visualizing molecular vibrations that highlight unique spectral responses in materials like minerals or semiconductors. The latest systems feature a spectral range of 220-380 nm, built-in illumination, capture and analysis computer and software, and safety enclosure (essential because prolonged exposure to deep UV can be harmful to the user).This is a wavelength range that may offer benefits to applications such as industrial metrology, pharmacology, food ingredient analysis, and art and forensic analysis. The presentation will include a discussion of such a system’s unique capabilities and an example of its use.
