Supervisor:

Department of Computer Systems

Synopsis:

The aim of this course is to acquaint students with optical measurement methods from the detection of microparticles, non-regulation and surface breaches, through the use of fiber optics in areas where it is not possible to use standard electronic sensors, or in places with increased risk of explosion and in hospitals, lidars used in intelligent transport infrastructures, to macroscopic sensing (remote sensing) of the Earth, atmosphere and space. The inclusion of these measurement methods requires in particular an understanding of the physical mechanisms on which they are based, as well as knowledge of measurement procedures and specifics in data processing and reconstruction.

Requirements:

Syllabus of lectures:

1. Introduction to optics, overview of sensors.

2. Description of optical sensor systems, comparison of generation and signal detection capabilities, interferometric approaches.

3. Detection of liquids/gases use of principles of refractometry, spectroscopy and polarization of light.

4. Optical sensors for medical purposes and sensors in aviation (gyroscope).

5. Monitoring of technical state of surfaces and structures (structural health monitoring) use of fibre grids (FBG - Fibre Bragg grating).

6. Monitoring of technical state of structures distributed fibre reflectometer sensors (OTDR) - coherent, polarization, Raman and Brillouin reflectometer.

7. Optical scanners passive, properties of sensing systems (CMOS, CCD, APD, EMCCD), noise sources.

8. Optical scanners active, 3D reconstruction.

9. Optical inspection of objects, defectoscopy.

10. Lidary concept, parameters, accuracy of detection, applications in automotive applications.

11. Atmospheric layers, passage of optical waves through layered environment.

12. Remote sensing of the Earth - spectral properties of the surface, profile and position measurements, combinations of radiometrological data, hyperspectral sensing.

13. Remote sensing of the Earth - rectification and reconstruction of the metrological image. Remote sensing of the Universe.
