Laboratory of Holography

Album

the HeNe laser and part of the instrumentation of the laboratory

SHORT DESCRIPTION 

The laboratory is dedicated to teaching activities for the first cycle degree in Physics, concerning digital holography.   In particular, the laboratory is equipped with instrumentation that allows students to perform the compulsory internship for their first cycle thesis. 

INSTRUMENTATION 

  • Laser HeNe, P = 30 mW , l = 630 nm. 
  • Michelson interferometer. 
  • Lenses, mirrors, beam splitters, intensity attenuators. 
  • CCD camera connected to a personal computer. 

TEACHING AND TRAINING

The instrumentation available in the laboratory allows students to record digital holograms by a CCD camera connected to a personal computer. Holograms are then reconstructed through a Matlab software. Several  
first cycle degree theses in Physics have been so far completed.
