Position: Scientist or a doctoral candidate specializing in physics, engineering sciences, applied mathematics or a similar subject
Institution: Physikalisch-Technische Bundesanstalt
Location: Braunschweig, Niedersachsen, Germany
Duties: Imaging experiments by means of simulations has gained in importance. By doing so, virtual measuring instruments are created, which can then be thoroughly investigated using mathematical methods. for this purpose, a Competence Center called "Metrology for Virtual Measuring Instruments" has been set up at PTB. Within the scope of this Competence Center, one of the tasks will consist in further developing a computer-based optical measuring system - the tilted-wave interferometer (TWI) - which is used to measure the form of aspheres and free-form surfaces. The TWI records several interferograms that are then evaluated using the model of the measuring instrument. This implies solving inverse problems, i.e. determining the properties of the EUT by replicating the measured data in a model. Your tasks in more detail: Carrying out real and virtual measurements; Developing methods to validate the simulations; Investigating the model-based measuring system as to its uncertainty; Developing new numerical and statistical data analysis procedures (e.g. using machine learning); Participating in the "Metrology for virtual measuring instruments" Competence Center; Writing publications and presenting the results obtained at conferences
Requirements: You have completed university studies (Master's or German Diplom ) in physics, engineering sciences, applied mathematics or in a comparable field and have obtained at least the grade "good" You have experience in at least one of the following fields: optical metrology, developing numerical/statistical procedures, machine learning methods; You have practical programming experience (e.g. Matlab, Python or similar); You have excellent communication skills and are a team player; You are highly committed, capable of working autonomously and willing to improve your skills; You have a good command of German and English and are able to present results convincingly, both in spoken and in written language; You are willing to travel within Germany as well as abroad within the scope of your assignments
