Interferometric controls / Labwork
The source code of the application is in the applis/Zygo-labwork directory of the GitHub repository of this project : Camera GUI.
Goal of the labworks
The topics of the lab sessions are available on the LEnsE website:
First year: Interferometric Controls (French version only) Second year: Aberrations
First series of labworks : quality of standard optical components
These lab sessions aim to present some commonly used interferometry methods for characterizing the quality of standard optical components (parallel-faced plates, flat mirrors, telescope mirrors, optical systems, etc.). These techniques allow the quantification of the quality of finished optical components or those in the process of manufacturing.

Second series of labworks : aberrations
The goal of the following lab sessions is to study and analyze the defects of an optical system, i.e. the geometrical and chromatic aberrations.

Needs for the interface
ZYGO is a Fizeau laser interferometer (using an amplitude division) equipped with a phase shift system. It allows to measure wavefront errors down to approximately λ/10(PV).
The user interface of the ZygoLab application is designed to facilitate the acquisition and analysis of interferograms obtained using a Zygo interferometer as part of the photonics lab work at the Experimental Teaching Laboratory (LEnsE) of the Institut d’Optique Graduate School (IOGS).
