Abstract
In this study we have designed, assembled, and characterized a wavefront sensor that works with defocused intensity images and the wavefront phase imaging (WFPI) algorithm. This approach allows for the potential utilization of the entire sensor surface, enabling high-resolution operation. This sensor, equipped with an electrically tuneable lens (ETL), performs focus movements of more than 60 Hz, enough for real time applications. We have developed numerical tools, as a practical software environment, with a graphical user interface (GUI), to make the camera a versatile instrument easily adaptable to different experimental setups without drastic changes in the optical configuration. These tools allow to analyse the wavefront in real time to extract the desired metrics and results.
