Position: Scientist, preferably with a doctorate specializing in physics, engineering sciences, applied mathematics or a similar subject
Institution: Physikalisch-Technische Bundesanstalt
Location: Braunschweig, Niedersachsen, Germany
Duties: Optical imaging systems are a key element in numerous high-tech applications. PTB departments 4.2 and 8.4 have been successfully cooperating for several years in this field; they therefore have excellent contacts with the industry. One of the latest developments consists in imaging experiments by means of simulations. 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 and implementing new numerical and statistical data analysis procedures
Requirements: You have completed university studies in physics, engineering sciences, applied mathematics or in a comparable field. Ideally, you have obtained a doctorate; You have experience in implementing numerical models (e.g. using Matlab); Experience in optical metrology and/or in developing numerical/statistical procedures would be an advantage; You have excellent communication skills and are a team player; You are highly committed, capable of working independently 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
   
Text: scientist, preferably with a doctorate specializing in physics, engineering sciences, applied mathematics or a similar subject (19-172-4/8) Monday, 13.
