INTERNSHIP - Optics - Closed-loop caracterization and control of ultrafast tip/tilt platforms

BERTIN ALPAO, a subsidiary of the BERTIN TECHNOLOGIES group, is a high-tech company renowned for its innovation and expertise in adaptive optics (AO).

A world leader in this field, we design and produce a wide range of deformable mirrors (DM), wavefront sensors (WFS) and customized systems, specially designed for demanding applications such as space, astronomy, optical and quantum communications, ophthalmology, microscopy, microelectronics and laser applications. Thanks to our unique technology, we enable our users to correct optical aberrations in real time, thus obtaining very high-resolution images.

Over 90% exported, Bertin Alpao takes on multidisciplinary technological and scientific challenges in the service of international research projects. In particular, we have developed deformable mirrors for the world's largest telescope, and collaborated with the Nobel Prize-winning physics team Reinhard GENZEL and Andrea GHEZ, equipping a key instrument used for research into the Milky Way's supermassive black hole.

Our partners include prestigious players in the fields of research, such as ESO (European Space Observatory), NASA and CNES, and industry, such as Airbus, Thales and Safran...

Located in "Inovallée" in Montbonnot Saint-martin (38), in the heart of Europe's "Silicon Valley", we offer our 50 employees a unique working environment at the foot of the Alps.

Do you enjoy challenges? Are you curious and keen to undertake an internship that will help you develop and put your academic skills into practice? Would you like to join an innovative and agile company and contribute to its sustained growth?

To help us achieve our performance goals, we are continuing to pursue our ambitions and strengthening our teams at our subsidiary Bertin Alpao. So join us as part of our internship topic entititled: Closed-loop caracterization and control of ultrafast tip/tilt platforms for atmospheric turbulence correction in adaptive optics.

As Bertin Alpao's market share in FSO application increases, we aim to strengthen our ability to design complex optical systems that meet the specific needs of our clients. In this context, qualifying key components such as fast Tip/Tilt mirror platforms (TTM) is a crucial step in the design of our advanced optical systems.

The goal of this internship is to measure and validate the performance of components offered by our TTM platform suppliers.

Your main Tasks will consist in Design and assembly of an optical test bench dedicated to the characterization of Tip/Tilt platforms :

• Redaction of a test plan for dynamic performance caracterization
• Measurement of the transfer function and bandwidth of the selected products
• Comparison between experimental results and theoretical models
• Writing of a technical report summarizing results and recommendations.

You are an engineering or Master student (4th year), specializing in optics, instrumentation, or applied physics.

Your academic backgrouds has enabled you to develop knowledge and skills in the following technical areas :

• Knowledge in optics, signal processing, and instrumentation
• Scientific rigor, autonomy, and analytical mindset
• Prior experience in laboratory work, optical bench assembly, or control theory would be a plus.

Are you known for your adaptability, rigor, and team spirit?

Do you enjoy working independently and in an organized manner in a challenging environment?

Finally, do you share our core values of courage, confidence, talent, and team spirit?

Then don't hesitate to apply
