Jürgen Czarske has studied electrical engineering
Electrical engineering
Electrical engineering is a field of engineering that generally deals with the study and application of electricity, electronics and electromagnetism. The field first became an identifiable occupation in the late nineteenth century after commercialization of the electric telegraph and electrical...

 and physics at University of Hanover
Leibniz University of Hannover
The University of Hanover, officially the Gottfried Wilhelm Leibniz Universität Hannover or LUH, is a university located in Hanover, Germany. It was founded in 1831 and is one of the oldest universities focussing on science and technology in Germany...

. At the same university he received the Ph.D. degree on 9 February 1995 and the degree of Dr.-Ing. habil. (habilitation) from faculty of mechanical engineering
Mechanical engineering
Mechanical engineering is a discipline of engineering that applies the principles of physics and materials science for analysis, design, manufacturing, and maintenance of mechanical systems. It is the branch of engineering that involves the production and usage of heat and mechanical power for the...

From 1 October 1995 until 14 December 2004 he has worked at Laser Zentrum Hannover e.V. (private research institute of applied laser science
Laser science
Laser science or laser physics is a branch of optics that describes the theory and practice of lasers.Laser science is principally concerned with quantum electronics, laser construction, optical cavity design, the physics of producing a population inversion in laser media, and the temporal...

), Hannover. Since 15 December 2004 he is with the University of Technology in Dresden. In the faculty of electrical engineering and information techniques he leads the laboratory of measurement and testing techniques. His main interests are laser sensors with high spatial
Angular resolution
Angular resolution, or spatial resolution, describes the ability of any image-forming device such as an optical or radio telescope, a microscope, a camera, or an eye, to distinguish small details of an object...

 and temporal resolution
Temporal resolution
Temporal resolution refers to the precision of a measurement with respect to time. Often there is a tradeoff between temporal resolution of a measurement and its spatial resolution. This trade-off can be attributed to the finite speed of light and the fact that it takes a certain period of time...

. He has applied these sensors in aerodynamics
Aerodynamics
Aerodynamics is a branch of dynamics concerned with studying the motion of air, particularly when it interacts with a moving object. Aerodynamics is a subfield of fluid dynamics and gas dynamics, with much theory shared between them. Aerodynamics is often used synonymously with gas dynamics, with...

 for the investigation of turbulence
Turbulence
In fluid dynamics, turbulence or turbulent flow is a flow regime characterized by chaotic and stochastic property changes. This includes low momentum diffusion, high momentum convection, and rapid variation of pressure and velocity in space and time...

 phenomena.

The laser sensors also have been used in manufacturing metrology
Metrology
Metrology is the science of measurement. Metrology includes all theoretical and practical aspects of measurement. The word comes from Greek μέτρον , "measure" + "λόγος" , amongst others meaning "speech, oration, discourse, quote, study, calculation, reason"...
