Internal Research Fellow PostDoc in Adaptive Optics with Laser Guide Stars

2018-08-08 11:27:15| Space-careers.com Jobs RSS

Research Fellowship Opportunity in the Directorate of Telecommunications and Integrated Applications. ESA is an equal opportunity employer, committed to achieving diversity within the workforce and creating an inclusive working environment. Applications from women are encouraged. Post Internal Research Fellow PostDoc in Adaptive Optics with Laser Guide Stars This post is classified F2. Location ESTEC, Noordwijk, The Netherlands Our team and mission The research position will be in the GovSatCom and Secure Communications Section of the Institutional and European Programme Office, Telecommunication Technologies, Products and Systems Department, which is part of the Directorate of Telecommunications and Integrated Applications. The proposed field of research is of relevance for future spaceground optical communications, which is one of the main topics of the ScyLight Programme. The work to be performed will be supervised by the OptoElectronics Section of the Mechatronics and Optics, Division, which is part of the Directorate of Technology, Engineering and Quality. Among other areas of expertise, the Optoelectronics Section deals withsupports the development of optical communication systems e.g. EDRS, Optelmu, Second Generation GNSS, optical ground station operations and it is also in charge of ESAs Optical Ground Station. Interested candidates are encouraged to visit the ESA website related to the Divisions activities Fields of activitiesresearch The field of research will be in the area of adaptive optics with laser guider stars, with the final application of laser communications through the atmosphere. Laser beam characteristics degrade due to detrimental effects such as scintillation, beam spreading, beam wandering, angle of arrival fluctuations and wavefront distortion, caused by the propagation through a turbulent medium like the atmosphere. In practical terms, the laser beam is distorted such that the detection and recovery of the communications signal modulating the optical carrier is severely affected in terms of quality of service bit error probability and availability. Countermeasures need to be implemented in order to correctminimize atmospheric turbulence effects. In most cases, part of the received signal is used as a reference to evaluate the disturbance and to determine the amount of correction needed to apply to the incoming optical signal, and also to the outgoing optical signal so called precompensation or predistortion. However, in some cases the distortion of the received signal cannot be used to predistort the outgoing signal because the angular separation between the incoming and the outgoing optical signals is so large that the turbulence effects in both directions are uncorrelated i.e., the point ahead angle can be larger than the isoplanatic angle in some scenarios. In this case, one could envisage placing a laser guide star in the direction of the outgoing laser beam and using the distortion sensed by the received light from the laser guide star to predistort the wavefront of the outgoing laser beam. In this context, the Research Fellow will participate in measurement campaigns and will analyze the resulting data of an experiment assessing the feasibility of using a laser guide star for laser communications through the atmosphere. The Research Fellow will investigate how to extract the wavefront distortion information of the laser guide star in a way that this information can be used to correctpredistort the wavefront of the outgoing laser beam, such that the reception at the counterpart location is optimized. The research will be carried out in close cooperation with other investigators from ESO European Southern Observatory and DLR German Aerospace Centre. Technical competencies Ability to conduct research autonomously Breadth of exposure coming from past andor current researchactivities Researchpublication record Knowledge relevant to the field of research Interest in space and space research Ability to gather and share relevant information Behavioural competencies Innovation Creativity Continuous Learning Relationship Management Self Motivation Communication Problem Solving CrossCultural Sensitivity Education Applicants should have recently completed, or be close to completion of a PhD in a related technical or scientific discipline, preferably in physics or mathematics or engineering. Preference will be given to applications submitted by candidates within five years of receiving their PhD.

Knowledge of laser communications and atmospheric turbulence would be an asset. A background in statistics and random processes, and in imaging processing, is required. The Research Fellow must be able to work in a team with other international investigators in a spirit of positive cooperation and, at the same time, be capable of working autonomously in hisher area of research. At the end of the fellowship, the Research Fellow will be required to summarize the work completed so that it can be included in papers to be submitted to specialised conferencesjournals in the field of laser communications for space e.g., SPIE, ICSO, ICSOS, IEEE. The working languages of the Agency are English and French. A good knowledge of one of these is required. Knowledge of another Member State language would be an asset Other information For behavioural competencies expected from ESA staff in general, please refer to the ESA Competency Framework.
