LABORATORY OF OPTICAL AND LASER METROLOGY

Assen Shoulev, Simeon Karpuzov

More than 25 years in the optical laboratory of IMech, the mechanical properties and characteristics of different objects, materials, and mechatronic systems have been successfully studied. Recently various composite materials have been explored for the purpose of civil engineering and the results have found application in the modern European industry. The latest research projects were focused on development and investigation of Micro Electro Mechanical Systems, Micro Fluidic Devices, Micro Manipulation of Biological Cells, and Robotic Systems for Invitro Fertilization.

During the last 10 years we have published more than 50 articles and participated in 10 scientific projects.


 

Our optical laboratory consists of two equipped rooms suitable for conducting precise optical experiments and two auxiliary rooms. The laboratory has a large concrete vibrо-isolated table, several granite and metal optic benches with universal and specialized riders and holders, lasers, variety of optical components, digital cameras, precise position modules, optomechatronic systems, controllers, electronic measurement equipment, computers, etc.
