What does the Centre do?
At the Centre for Laser Engineering and Holography, we explore the application of lasers in optoelectronic measurement systems, focusing on holographic measurement techniques. In a word, we deal with light.
Light has properties (colour is one of them) that change under external influence. Various physical quantities, such as speed or force, can be calculated by measuring these changes. Lasers are light sources that produce directional beams of very "pure" colour, which is why they have a wide range of applications, from scanning QR codes in stores to very precise navigation using gyroscopes in spacecraft. Most information today is transmitted through optical fibres using light (as in the case of the Internet), where lasers are used as the light source. Light-based measurements, like holography itself, rely on coherent laser light. A hologram can be understood as a photograph that, in addition to information about the colour distribution, also carries information about the wavefront of light. That is why a hologram has a much higher information content than an ordinary photograph.
