Dynamic Interferometry for Metrology Workshop 🗓 🗺

With Live Demonstrations

Quantum Design and 4D Technology are proud to announce that we will be holding a workshop “Dynamic Interferometry for Metrology” at the OpTIC Technology Centre, Glyndŵr University, St Asaph on 16 March 2023. 

The workshop will cover the theory and practical aspects of dynamic interferometry:

• Interferometry principles for 3D shape and transmitted wavefront measurements
• Dynamic interferometry – what it is, how it works
• Unique capabilities using dynamic interferometry

---

The day will consist of live demonstrations:

Operate 4 different optical metrology systems with hands-on demos. See the principles in practice, with Q&A and examples. You can:

• Try it yourself: Make a micron-level 3D measurement with a handheld optical gauge
• See an interferometer measure a optic in 30 microseconds without vibration isolation
• Learn how to separate surface measurements of a transparent concentric dome

The workshop is free of charge and will include lunch and refreshments.  Early registration is recommended as spaces will be limited.

About 4D Technology  

For over 20 years, 4D Technology has been a leader in innovative metrology products for measuring surface quality and surface defects on precision surfaces, as well as the surface and wavefront quality of optics. 4D’s patented Dynamic Interferometry® technology enables measurements in difficult environments, where vibration, air turbulence or rapid motion have traditionally prevented accurate measurement.    

During that time, 4D interferometers have been used to assure the quality of some of science’s most challenging telescope projects, both terrestrial and in space. An early customer was NASA, which used several instruments to measure the James Webb Space Telescopes multi-mirror components, the alignment of those mirrors, and the supporting structure for them, both in air and in cryo- and vacuum-chamber tests.  

New instruments in surprising situations 

Using unique and proprietary dynamic measurement techniques, 4D Technology’s award-winning laser interferometer technology is used in to a wide variety of applications, including: 

• factory-floor inspection 
• telescope mirrors and systems 
• biomedical research 
• environmental sensing and imaging 

• and much more
