Laser measuring systems

assoc. prof. dr. Matija Jezeršek

Study materials and information on current events and assessments can be found on the student website of the Faculty of Mechanical Engineering.

Short description:

Lectures and tutorials cover laser systems for measuring distances, speeds, 3d surface shapes at micro and macro levels and 3d deformations. Lab work is an important part of the course, where the content of the lectures is tested and upgraded so that students create measurement systems, perform test measurements with them, and process and interpret the data appropriately.


The following pre-knowledge is recommended for successful study:

•            Physics (geometry optics, wave optics)

•            Basic principles of lasers

•            Mechatronics

•            Computer programming

Content (Syllabus outline):

  1. Building blocks of laser measurement systems
  2. Interferometry
  3. Laser triangulation technique for 3d scanning
  4. Calibration techniques
  5. 3d measurement using Time-of-flight principle
  6. Post-processing of measured data

Objectives and competences:

In scope of the Laser measurement systems course, the students will:

•            become aware of the significance of measurement technology,

•            earn the ability to select suitable measurement systems in the working process,

•            develop a perception about the continuous improvement of manufacturing and diagnostic processes.

The students will earn the following subject-specific competences:

•            knowing the fundamental principles of laser measurement technology,

•            knowing the characteristics, advantages and limitations of individual laser measurement methods,

•            knowing the applications of laser measurement systems,

•            practical knowledge in the field of development of laser measurement systems.

Intended learning outcomes:
