Our team and mission

The Optics Section, as part of the Optics, Robotics & Life Sciences Division, provides optical engineering support to ESA projects and carries out technological research in the areas of optical component technology, optical instrumentation (spectro-radiometric imaging instruments in the visible and infrared, interferometry, optical aperture synthesis) and testing (calibration and performance verification).

 

You are encouraged to visit the ESA website: http://www.esa.int

Field(s) of activity/research for the traineeship

As a trainee, you will be exposed to a wide range of activities addressed within the optics section. In assistance to ESA optical engineers, you will participate in the development of optical instruments for dedicated space projects, and you will be involved research and development activities of the corresponding optical technologies. In addition, you will be assigned to the optical engineering tasks as outlined in the following paragraphs, which you will focus on during your traineeship.

 

  1. the optical design and performance prediction of optical instrumentation relies on commercial software tools. You will have the task to explore possibilities, evaluate limitations of existing software/software under development and help in adding additional functionalities required for the design of novel instruments.
  2. Adding functionality to allow the performance simulation of optical designs employing non-classical components, such as meta-optical elements.

 

Throughout your traineeship, you will collaborate with a multidisciplinary team of engineers and scientists, gaining insights from their expertise while contributing your unique perspective. By the end of your internship, you will have gained valuable experience in the working principle of optical instruments for space applications in general, and polarization effects within multi- and hyperspectral imagers in particular. You will have acquired skills in using advanced optical simulation tools and you will have gained hands-on experience related to the characterization of optical components in a laboratory environment.

 

As part of your traineeship, you will also get the opportunity to learn about other activities and projects that the section is involved in.
