| Announced Project: |
| Computational imaging using vector optical beams generated from micro/nano optical devices (supervisors Vijayakumar Anand, Aile Tamm) Computational imaging is one of the rapidly evolving areas of imaging. Most of the computational imaging methods transform the object information into a summation of shifted and scaled scalar optical fields. The resulting intensity distribution read by the image sensor is reconstructed into object information. This PhD project titled, “Computational imaging using vector optical beams generated from micro/nano optical devices,” aims to employ vector optical fields as the building block of the intensity distribution. Consequently, the summation is no longer a scalar summation but a vector one making it sensitive to changes in polarization of the object along 3D spatial and spectral dimensions. The existing computational reconstruction methods are only suitable for scalar optical fields. This PhD project will create new knowledge on vector convolution and correlation. The vector optical fields will be generated using novel engineered polarization sensitive micro/nano optical modulators. The modulators will be manufactured using advanced lithography procedures and implemented for experimental demonstration. Novel multidimensional compact, light-weight microscopes will be realized using the new vector correlation principles beyond the state-of-the-art. |

EXPIRED - Recruitment process completed
Ph.D. projects in computational imaging (optics/photonics/physics) with junior scientist salary/scholarship (open to everyone)
Starting date: 1st September 2022
Duration: 4 years
Funding: Junior Scientist Salary
Location: Center of Photonics and Computational Imaging, University of Tartu, Estonia, Europe
Computational imaging uses computational methods to enhance the image quality, resolution or add spatial dimension to the image beyond the physical or technical limits of the imaging system. It has applications in microscopy, medicine, robotics, remote sensing and astronomy and the range of applications increases with advances in sensor technology, computer algorithms and on-board computing capacity which by nature makes the research interdisciplinary.
We are recruiting 2 PhD students for a fully funded PhD positions in Computational Imaging/Optics/Photonics/Physics for a period of 48 months with a start date in September 2022 within the Computational Imaging Group, Lab of Physical Optics, Institute of Physics, Faculty of Science and Technology, University of Tartu. The position is supported by European Union’s Horizon 2020 research and innovation programme under grant agreement No 857627 CIPHR - Computational Imaging and Processing in High Resolution.
You will join our team not only as a PhD student but as a junior researcher with all the perks and responsibilities. You can sharpen your scientific profile in an evolving and exciting research environment and advance in your professional career. We offer a scientifically and intellectually inspiring atmosphere.
About the projects:
1. Multispectral multidimensional imaging using an ensemble of self-interfering spatially incoherent chaotic scalar waves
In the recent years, chaos-inspired imaging technologies (CI2-Tech) have gained a lot of attention. Most of the CI2-Tech approaches involve scattering of the light diffracted from an object to distinctly encode many spatio-spectral information channels in one intensity distribution. The doctoral project titled “Multispectral multidimensional imaging using an ensemble of self-interfering spatially incoherent chaotic scalar waves,” unifies all the existing CI2-Tech methods under a single roof. The doctoral project aims to create a computational optics framework for statistical optical experiments. In this framework, an ensemble of chaotic scalar waves with interesting intensity distributions can be synthesized, their composition and mutual interactions can be controlled. The project aims to access the non-linear regions of imaging characteristics by mapping every object point to an ensemble of special optical intensity distributions. Consequently, the previous CI2-Tech methods are only a special case in the proposed framework. The doctoral thesis aims to create a novel hybrid reconstruction algorithm based on cross-correlation, maximum likelihood and optimization to reconstruct the recorded intensity distributions into a 5D image. The doctoral project will generate new knowledge in statistical optics, reconstruction mechanisms and imaging technologies which has potential for developing advanced optical microscopes.
2. Interferenceless coded aperture correlation holography with deterministic optical fields Interferenceless coded aperture correlation holography (I-COACH) is an incoherent holography technique capable of reproducing three-dimensional (3D) information of an object from a single camera shot.
In I-COACH, the light from an object was modulated by a quasi-random phase mask and the scattered intensity pattern was recorded by an image sensor. The 3D object information was reconstructed by processing the object intensity pattern with the pre-recorded 3D PSF distributions. While I-COACH can record and reconstruct 3D information without two beam interference unlike its’ precursors such as self-interference digital holography methods, it is not without problems. The need for scattering in I-COACH and the need for recording PSFs increases the noise and reduces the resolving power respectively. The speckle distribution generated in I-COACH and the reconstruction mechanism involving cross-correlation with PSF precludes the introduction of special imaging characteristics. The doctoral thesis titled “Interferenceless coded aperture correlation holography with deterministic optical fields,” is a game changing approach which is expected to address the above challenges of I-COACH and expand the applicability of I-COACH to power sensitive areas. The proposed doctoral thesis will investigate the special beams with interesting spatial intensity distributions for 3D imaging applications. The doctoral thesis will create a unified artificial intelligence-based image reconstruction algorithm for reconstruction of 3D information for special beams. The outcome of the doctoral thesis is expected to lay the foundations of a new generation of imaging and microscopy technologies.
