The main objectives of this course is the specialization of students’ knowledge and the acquisition of skills in selected technological applications topics based on the interaction of radiation with matter, optical instruments and complex optical systems technologies, laser technologies and photonics.

Upon successful completion of the course students will be able to:

  • explain to non-experts the interaction of radiation with matter taking into account elements from quantum mechanics,
  • design complex optical systems and identify their characteristics,
  • critically evaluate the different types and technologies of lasers, their operation characteristics and their applications in industry, in telecommunications, in information technologies, in remote sensing and geoinformatics,
  • identify the characteristics of fiber optics and evaluate their applications in optical communications,
  • identify and critically evaluate interferometry techniques and their applications,
  • determine the characteristics of spectrometers, radiation detection and spectral analysis technologies,
  • analyze and take advantage of upcoming technological developments in the field of photonics and critically evaluate their effect on geoinformatics, information technologies and telecommunications,
  • evaluate bibliographic sources for the study of research topics in various scientific areas of Optics and Lasers,
  • collaborate with their colleagues for the preparation and presentation of an experimental project.

Assessment language: Greek (English for ERASMUS students upon request)
Performance evaluation method:
• Final Written Exam (60% of the final grade) of graded difficulty, which may include short-answer questions, open-ended questions and solving simple and complex problems.
• Evaluation of the individual research project and its presentation using ICT (20% of the final grade).
• Evaluation of laboratory work and its presentation using ICT (20% of the final grade).

The evaluation criteria have been presented to the students before the final examination. Students can see their evaluation upon request and receive clarifications on their grades.
