Tutorials
At EOSAM 2025, as in previous EOSAM conferences, in addition to the conference program including contributed and invited speakers, we wish to provide an additional benefit to all registered attendees in the form of tutorials covering Topical Meeting (TOM) and Focused session topics. These tutorials will take place on Sunday, 24 August 2025.
Participation in these tutorials is free for all registered conference attendees, but pre-registration is required for each tutorial. Registration will open by April 2025.

Introduction to Colorimetry
This course introduces the physiology of human color vision, the common CIE color spaces, color difference metrics and color rendering metrics.
An easy-to-grasp, intuitive visualization of additive color mixing in the common CIE 1931 XYZ color space is explained.
Practical examples of colorimetric computations are presented, interactively with a freeware GUI program, and programmatically, using free, open source Matlab and Python libraries.
Julius's tutorial will concern at least the following TOMs:

About the Speaker
Julius Muschaweck, a German physicist, has been working on optical design for illumination for almost thirty years.
He was co-founder and CEO of OEC, an optical engineering service which pioneered freeform optics for illumination.
Later, at OSRAM, where he held the position of Senior Principal Key Expert, he coordinated the over 100 optical designers within OSRAM world-wide.
He then joined ARRI, the leading movie camera and lamp head maker, as Principal Optical Scientist.
Julius Muschaweck now works as an independent consultant, providing illumination optics solutions to industry clients, teaching courses on illumination optics, and writing about the subject.
He is the author of over 25 scientific papers and the inventor of over 50 patent applications.

Spatial Light Modulators
Spatial Light Modulators (SLM) have become common devices in Optics in Photonics laboratories. They are high-resolution micro-displays useful for displaying reconfigurable intensity, phase or polarization spatial patterns, thus being key components in adaptive optics and programmable diffractive optics. This tutorial will present the fundamentals of SLM technology, their modulation configurations and techniques for their characterization. The tutorial will also cover the design of diffractive optical elements and its realization with SLMs.
The tutorial will include a practical demonstration from the company Holoeye Photonics (Home - HOLOEYE Photonics AG), one of the major suppliers of SLMs.
Ignacio's tutorial will concern at least the following TOMs and Sessions:
- Face2Phase
- TOM: Adaptive and Freeform Optics
- TOM: Applications of Optics and Photonics
- FS: Visual Optics and Imaging
About the Speaker
Ignacio Moreno is Full Professor of Optics at Universidad Miguel Hernández of Elche, where he leads the TecnOpto Lab. He has extensive experience in the field of liquid crystal spatial light modulators, and their application in diffractive optics and polarization optics, being coauthor of more than 180 articles published in peer reviewed journals. He is Fellow member of SPIE and OPTICA. For 10 years he was associate editor of the journal Optical Engineering for the subject of optoelectronic displays, where he leaded two special issues devoted to “Liquid Crystals for Photonics” (2011), and to “Spatial Light Modulators: Devices & Applications” (2019).
