RealHolo – More than Meets the Eye
RealHolo is an EU-funded project aiming to produce a reflective, micro-mirror array, spatial light modulator with the aim to “pave the way for mainstream mixed reality environments”, quoting the project site verbatim. However, if we pop the hood and look inside, we will find that with the specifications and technical targets already achieved, RealHolo is…

WaveMe’s Evolution: Tools and Techniques for Peak Performance
WaveMe Toolbox: Enhancing Optical Metrology and Empowering Users The WaveMe toolbox exemplifies several core principles that I hold in high regard: advancing optical metrology, getting the most from standard equipment, and offering users more control over their tools. A recent development further underlines our commitment to these principles. WaveMe is flexible as it allows users…

Introduction to Goodman’s Graphical Methods
This blog post will be the first of three about the appliation of Goodman’s graphical methods and partially coherent illumination with focus on its application to spatial light modulators. This introduction will start at a point before Goodman’s paper and end just about where his paper begins. Hopefully, it will serve as an introduction to…

WaveMe Toolbox: The Phase-Shifting and Trigger Tools
As as warm-up for the release of the WaveMe product, a first short video of the software has been made public. This software, although still alpha, should give a hint what the WaveMe product is all about. This demo uses prerecorded images but contains all necessary synchronization to perform the phase-shifting measurement. The Blender image…

Spatial Light Modulators
One of the more complex photonic devices one will encounter as an optical engineer is the spatial light modulator. This is a device that (usually) converts a computer-generated signal into a spatially controlled distribution of intensity or phase, depending on the type of modulator. A very well-known device for intensity modulation is the DLP or…

The Challenge with Optical System Design
How should we approach the development and integration of a new complex, high-performance optical system? First, let us clarify what an optical system is. If you look around the Internet, you will find many companies offering optical system development services, but all we get to see is an objective, albeit one with many elements in…
