Photonics Hub Online Seminar: Basics of Optical Measuring Techniques Part I

Light can be used in many ways, as an information carrier in metrology, as a tool in material processing or as a data carrier in information technology. The advantage of using light is to realize non-contact measuring methods, i.e. non-destructive testing, which also works very fast for 2d or even 3d problems.

Photonics Hub likes to launch an online seminar series regarding optical measurement techniques. We want to discuss how various optical instruments like interferometers or microscopes work for example to operate 3d surface measurements.

Also you are not a specialist involved in developing or building measurement systems, to understand optical measurement systems ensures that you will be able to define the right system to meet your company’s current or future needs.

To understand optical measuring systems work, we start with a brief introduction of the basics of optical instruments. The physical background as well as the mode of operation of the needed optical components will be explained in the first seminar, discussing the following topics:

Basics of optical instruments:

  • The optical Image:  Magnification and Resolution
  • Principles of Spectrometer, Telescopes and Microscopes

The following Photonics Hub Online Seminars of this series will explain the technique of interferometry as well as interferometer types and finally the state of the art of 3d-measument technologies.
