Description

• In this experiment, we can study the two beam interference.
• The Mach–Zehnder interferometer is a device for demonstrating interference by division of amplitude.
• A light beam is ?rst split into two parts by a beam splitter and then recombined by a second beam splitter.
• Depending on the relative phase acquired by the beam along the two paths the second beam splitter will re?ect the beam with ef?ciency between 0 and 100%.
