Introducing Senslogic and WaveMe: Closing the Gap Between Optical Design and Reality
This tech talk is about Senslogic and the philosophy behind it. After over two decades in optics, one realization stands out, which is that there is a disconnect between theory and practice. Maybe the joke that “it works in theory” has some merit. Obviously, this is not the case everywhere, but it is so frequently…

Shack-Hartmann Wavefront Sensor Calibration in WaveMe
Calibration and Why it is Needed The WaveMe toolbox has a rather exceptional calibration method that allows for much more flexible use of the Shack-Hartmann wavefront sensor. This tech talk will be about what it is and why it is different from what is available elsewhere. We will assume that you, the reader, are already…

Analyzing Coupled Systems
Designing new optical systems from the ground up can be an intimidating task, especially if the system we are trying to make is one that we must get right before anything can be built because the critical components simply do not yet exist. It’s merely a figment of our imagination and it is actually part…

Designing a point diffraction interferometer
In this tech talk, we will dive a little deeper into the design of a point diffraction interferometer, or PDI for short. We have talked about it a little superficially in an earlier tech talk but this time, there should be enough for anybody who may consider building one. This application is well supported by…

WaveMe for Optical Alignment: The BeamNotes Tool
Introduction In the realm of optical engineering, achieving precise alignment between the optical elements within a system is crucial to ensuring optimal performance. This alignment is especially critical in compact optical systems like microscope lenses or other high-end optics. There are some well known brands here like Zeiss, Leica, Nikon or Tropel. They know what…

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…
