Appointment is for a period of three years. The position does not include teaching duties.

About the PhD-project

Background and project description: Miniaturized Computational Imaging Sensing Platform

A high resolution imaging microscope is an essential tool for seeing, identifying, tracking and quantifying interesting details in small objects, including bacteria, biological cells, live cell growth monitoring, micro-fluid based biomedical devices with online sensing, identifying and counting micro-plastics pollution in water, to name a few. Traditional imaging platforms are bulky and come with many limitations: resolution vs. field-of-view trade-off, CCD pixel count, phase imaging needs special optics, 3D information is lost.

We are working on combining computational imaging techniques (Fourier optics, ptychography, phase retrieval, super-resolution) with low-cost optics and cameras to overcome the above- mentioned limitations. The outcome of this work is that one can get a platform with gigapixel effective resolution with added information such as quantitative phase maps, anisotropic details, 3D layered phase information of the object under study. The term Computational Microscopy denotes recent efforts to improve microscopy-using computers as an active part of the image formation process, typically enabling better resolution, larger fields of view, improved contrast or 3D microscopy. Fourier Ptycography (FP) is a recently developed coherent diffraction imaging (CDI) technique dependent on partially coherent light and numerical phase retrieval.

We have a PhD position available at Department of Microsystems at USN in Horten. The PhD student will be part of bigger projects involving the development of computational microscopy techniques using Fourier ptychography methods in the visible and the X-ray wavelengths. We have worked on coherent imaging (speckle reduction, laser projectors, infrared imaging, Fourier ptychography in the visible and the X-ray regimes) and there are on-going projects on super-resolution imaging. There are currently several PhD students and postdoctoral researchers involved in these efforts. These projects are collaborations between the Department of Microsystems at USN in Horten and the Department of Physics at NTNU in Trondheim.

We plan to use additional degree of freedom of light to further enhance the information that can be extracted from the object (anisotropic details, 3D layered structure, 3D layered phase information). By using 3D packaging methods, it is intend to develop this computational polarization microscope into a low-cost miniaturized component (few cm3 volume) so that is can be used universally in the field or incorporated as a compact module with existing microfluidic devices. Further compactness and functionality can be achieved by using thin lenses made by MEMS technology and integrating a light source. The research will involve designing, construction of the hardware, fabricating meta-lenses and developing software for the imaging. Sophisticated analysis and modelling of large datasets will be an integral part of the work.

The main target research objectives of the project are:

  • Development of a compact visual-light Fourier ptychography microscope platform
  • Development of thin lenses for imaging
  • Algorithm and software development
  • FP microscopy studies of interesting sample systems

Information about the Department of Microsystems, USN

The Department's research spans a broad spectrum of applied microsystems. The Department's central research areas are: MEMS device technology, ultrasound devices, imaging optics and optoelectronics, materials science and BioMEMS technology. The Department is a part of Norwegian NorFab and NanoNetwork with access to all the facilities. It ha a modern clean-room with relevant equipment for device fabrication, packaging and characterization.


The successful candidate should hold a Master’s degree in physics, electrical engineering or photonics. The applicant must have gained the degree within commencement date.

It is a requirement that the successful applicant is granted admission to the university’s doctoral program in Applied Micro- and Nanosystems within three months after commencement, which requires an average grade B from Master’s degree, in addition to grade B at the final master project.

The position requires a strong interest in computational imaging, signal processing and data analysis. Experience from structural studies using scattering, diffraction or high resolution microscopy methods would be considered an advantage. Knowledge of Fourier optics, coherent imaging or microscopy (e.g. ptychography or holography) is desired. Strong computer programming skills (e.g. Matlab, Python or C) and hardware building skills are desired. Prior work in the clean-room for device fabrication would also be advantageous.

The successful candidates should be creative, ambitious and enthusiastic, with a strong ability to work independently and goal-oriented. He/she should enjoy interdisciplinary research and take keen interest in learning and working in teams, which is of particular importance in this multidisciplinary project.

The position require spoken and written fluency in English.
