Optical 3D Measurement Methods

RNDr. Pavel Pavlíček, Ph.D., SLO UP a FZÚ AV ČR, v.v.i., OLomouc

Optical 3D measurement methods are used to  measure shapes of objects precisely. They measure with no-contact and with the speed of light. So where may be problems?

11:30 – 12:00

The Czech Footprint in Astrophysics

Mgr. Jan Tomáštík, SLO UP a FZÚ AV ČR, v.v.i., Olomouc

Secrets of the universe are nowaday revealed with the significant help of Czech scientists, who contribute not only trough basic research, but also to the construction of telescopes on the opposite side of the planet. Ultra-high energetic cosmic rays (UHECR) are the most prominent carriers of deep space information. Detectors and telescopes from Prague and Olomouc are designed to their capture and analysis. This lecture will help you understand the role of Czech scientists and engineers in all of that.

12:00 – 12:30

Optical Micromanipulation Techniques

Ing. Petr Jákl, Ph.D., ÚPT AV ČR, v.v.i., Brno

Multi-Camera Surface Sensing Options for BTF Measurement

doc. Ing. Jan Hošek, Ph.D., ÚPRT FS ČVUT v spolupráci s KPGI ČVUT, Praha

The appearance of surfaces depends on the type and direction of illumination and the direction of observation, and therefore the actual surface perception depends on the conditions of its observation. This is a real-area virtualisation problem for Industry 4.0, where a faithful representation of the surface must be represented by a group of thousands of images taken with a combination of different lighting and observation directions. The lecture deals with the design and use of a device that can capture the set of thousands of images in minutes and the possibilities of using the BTF data.

13:00 – 13:30

Fiber Lasers – Basic Principles and Applications

Ing. Filip Todorov, Ph.D., ÚFE AV ČR, v.v.i., Praha

Fiber lasers are among the most impressive photonics achievements of the past years. They provide enough power for material cutting and welding but we can find lasers also in delicate devices being developed for the most precise measuring of time and frequency. It was the erbium doped fiber amplifier at the beginning of the laser technology boom - one of the key components needed for the fast internet expansion. The presentation will introduce the basic principles of fiber lasers some of their applications as well as some of the research results achieved at the Institute of Photonics and Electronics, Czech Academy of Sciences.

Reduction of structure dimensions introduced besides increase of elements density in integrated circuits also additional benefit in possibility of structure fabrication in a size of ones to tens of nanometers., which are able to significantly influence properties of optoelectronic devices such as LED or laser diodes. By implementation of structures such as nanodots, nanowires, nano pillars, quantum dots or photonic structures it is possible to enhance their properties and in the same time evade usual problems with lattice mismatch and stress in structure which cause mainly defects in semiconductors.
