Why Senslogic
Why choose Senslogic? A very reasonable question indeed. There is no shortage of established companies offering customized services that can handle solutions which include software, hardware and optics. Senslogic is but one and much less known. Low Overhead – And a Head Start One key reason to choose Senslogic is our low overhead. At a…

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…

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 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…

Point Diffraction Interferometer
The Smartt interferometer or its evolution, the Phase-shifting point diffraction interferometer is probably the most accurate one can make, and it is not even expensive. It has its limitation, doesn’t everything, such as that we need a focus to create a reference wave with a pinhole. If the focus is at a high numerical aperture,…

Wavefront Metrology
Optical wavefront metrology is a big subject. In this tech talk, we will focus on two topics which could even be considered dichotomies, phase-shifting interferometry and Shack-Hartmann wavefront metrology. With phase-shifting inteferometry, accuracy is key and every nanometer is significant. Speed and versatility comes second. Quite the opposite can be said for Shack-Hartmann wavefront metrology…
