Hot on the heels of Celtic comes the elegant ampersand of Encoder Medium. Also check out the massive Encoder Fat.
Ampersand of the Day
Today’s ampersand is brought to you by RM Celtic. It’s a fusion of the letters “E” and “T” from that font.
Windows of Opportunity – ENBW
When you search online for ENBW you’ll likely find a list of sites related to EnBW AG, a German energy giant (which, on a totally unrelated note, we were a customer of until recently). While energy is quite relevant in the context of this post, EnBW has nothing to do with it. This post is …

Since I have an account with facebook, LinkedIn, flickr, xing and who knows where else, I’m probably not expected to be too concerned about personal data privacy. But surprisingly I am. However, some of the benefits of participating on these sites (potentially) outweigh the drawbacks of giving out personal information. Also, on most sites, I …
Résumé Tuning
Letzte Woche war unglaublich erfolgreich, was die internationale Anerkennung meiner Forschungsarbeit in den vergangenen Jahren angeht. Nicht nur bin ich vom International Biography Centre zu einem der Top 100 Scientists 2011 gekührt worden. Nein, nur wenige Tage später gratulierte mir ein Brief vom American Biographical Institute zum Scientific Award of Excellence 2011.
Windows of Opportunity
Sometimes signals can be stubbornly non-periodic. This can make digital signal processing so much more annoying. The supposedly simple act of plotting the spectrum ends up being a game of trial-and-error, or requires making a decision that involves prior knowledge of what one would actually like to know in the first place. We’ll have a …
Scalar Diffraction – Fourier
In an earlier post we had a look at various diffraction formalisms that either originated in the Huygens-Fresnel principle or led to essentially the same results. The principle modeled a field distribution in a aperture (or on a surface) as a source of infinitely many spherical waves whose amplitudes and phases were prescribed by the …
Nature Photonics
After what seems (to me) to have been several eons worth of experimenting, writing, re-writing, re-experimenting, more re-writing and then some more re-writing (all of which mostly by others), the all-optical FFT idea that was used at the IPQ department at KIT finally made it into Nature Photonics. When I got there in late ’09, …
MATLAB anonymous functions
MATLAB is a programming environment I’ve been using for maybe eight or nine years. For most of this time I made use of anonymous functions, but I have to admit without really knowing what I was doing. I just copy-paste-modified the examples in the fzero and quad documentation and hoped they would somehow work. Which, …
Scalar Diffraction – Imagery
In this post on the principles of scalar diffraction there were quite a number of integral expressions for diffraction of light, starting from the Huygens-Fresnel principle and applying various degrees of approximation. Integral formulations are usually very abstract and not very illustrative. However, with today’s available computer power we can turn these integrals into…
