Osnova přednášek:

The lectures, in general, range from localized measurements (liquid, medicine, and aviation sensors via optical fibers and planar structures), through monitoring of the technical conditions of structures (structural health monitoring - bridges, pipelines, and buildings) to macroscopic remote measurements focusing on the atmosphere.

1. Introduction to optics, an overview of sensors

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

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

4. Optical sensors for medical purposes and for aviation (gyroscopes)

5. Monitoring of the technical condition of surfaces and structures (structural health monitoring) - use of Fiber Bragg gratings, FBGs

6. Monitoring of the technical condition of structures - distributed fiber reflectometric sensors (OTDR) - coherent, polarization, Raman and Brillouin based reflectometers

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

8. Optical scanners - active, 3D reconstruction

9. Optical inspection of objects, defectoscopy

10. Lidars - concept, parameters, detection accuracy, applications in automotive applications

11. Atmospheric layers, transmission of optical waves through a layered medium

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

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

14. Remote sensing

Osnova cvičení:

The seminars will combine theoretical background, where students will learn the basic optical mechanisms of propagation and especially signal processing, together with 2 blocks of practical measurements.

1. Recapitulation of necessary knowledge of optics and wave theory, electron optics

2. BeamPROP simulation software - optical wave guiding, single-mode fiber, wavelength-selective components

3. Measurements of 3-4. weeks - Detection of liquids by refractometry, sensors based on modified optical fibers

4. Measurements of 3-4. of the week - Fiber-optic gyroscope, detection of angular acceleration, data evaluation

5. Measurements of 5-6. of the week – strain sensing using optical fiber Bragg gratings - measurement of strain and temperature in the spectral region

6. Measurements of 5-6. weeks - length measurement with an interferometer - Michelson interferometer - incoherent variant / coherent variant

7. Seminar exercises - methods of data processing from 2D image, thresholding, histograms, statistics

8. Seminar - real data processing from optical scanner / lidar

9. Measurements of 9-11th week - Camera calibration - spectral sensitivity, dark current dependence, etc.

10. Measurements of 9-11th week - Spectra radiometer

11. Measurements of 9-11th week - 3D reconstruction

12. Seminar - processing of real measured signals (astronomical data, satellite measurements of Prague)

13. Seminars - classification and interpretation of satellite data

14. Check of semestral work
