BIOSKETCH: “I was born and raised in the northern part of Greece and I have studied Physics in the Aristotle University of Thessaloniki. Consequently, I moved to Sweden to continue my studies in a Master level and I obtained a MSc in Physics from Lund University. My specialization was in the area of photonics and computational electromagnetism, and the objective of my master thesis was the modeling of the light coupling to nanowire arrays, towards  optoelectronic and photovoltaic applications.

              I currently work as an Early Stage Researcher in the Marie Skłodowska-Curie project OUTCOME. The main objective of my PhD thesis is to develop a measurement method capable of detecting damage evolution in aircraft-wing structures before, during and after flight-tests and measure real-time initiation and progression of surface mechanical damage in aircraft structures. It is a very challenging and exciting project and the development of such a computational optical metrology will be a very important inspection tool for the aerospace industry.”

MONTHLY REPORT

20/12/2016:

“The first period of a PhD research project can be described as a walk in an unexplored area and is dominated with a certain level of confusion and uncertainty. One finds himself/herself introduced in too many new subjects, methods and even terminology. The main objective of this part is to acquire a more profound knowledge of the subject and the latest advances in the area of interest, via an extensive literature research. The exciting part is that the more you progress in this process and your degree of understanding increases, the more interested you become on the project and more motivated to work as a part of something that might lead to a new idea or produce novel knowledge.
This narrative describes my first two months of working in my PhD project. The picture is completed if we add the introduction to the Spanish culture, cuisine and language. Spanish people are always very friendly and welcome foreigners like me with a smile and positive attitude. In many ways the culture resembles the culture of my homeland and it was very easy for me to adjust to this new environment. The same positive atmosphere I encountered in my work place where my supervisors and co-workers in Sertec were always willing to help me and provide everything I need for my job. In this context, my next goal is to learn the Spanish language, since this will allow me to get to know further this beautiful city and integrate to the society.
I have a very good feeling about the project and I think that with hard work we will be able to produce nice results. This makes me very motivated and intrigued to investigate further this subject.”

“The work for the past few months of my research has involved mainly two basic directions: the simulation of the operation of the plenoptic camera and the design and preparation of a laboratory room for testing visual metrology systems in our facilities in Sertec.

We have developed an algorithm that based on the configuration of the different elements of the plenoptic camera simulates the ray propagation from a scene in the outside world of the camera, through the camera elements to the photosensor of the camera, where the final image is produced. This simulation allowed us to acquire a better understanding of the functionality of the camera and estimate how different parameters of the camera elements (focal length and aperture size of the main lens or the microlenses, distance between the lens and the microlens array etc.) influence the field of view and the depth of field of the camera as well as the resolution of the image. These parameters define the size of the surface area that the system is able to scan and the accuracy of the measurement, hence it is very important to know to tune them in order to optimise our results.

In addition, we have worked on the preparation of a laboratory room in our facilities that will offer ideal conditions for performing test measurements of the optical metrology system that we develop. This laboratory “dark room” is painted black, in order to eliminate the reflection from the walls, and it is equipped with a LCD monitor, two industrial cameras, two recently purchased plenoptic cameras and some auxiliary components. According to our plan, we will start performing 3D measurements using the industrial cameras and a projector in an active stereo vision set up. Consequently, we will perform the measurements with the plenoptic cameras in a configuration similar to stereo vision. To our best knowledge and after the state-of-the-art that we have performed during the previous months, the active stereo vision set up with two plenoptic cameras has not been investigated in the scientific bibliography and we are very intrigued to work on this set up and explore its capabilities.”
