The system proposed here consists of a phase camera formed by microlenses placed at the focus of a converging lens, and whose data, interpreted by the combined technique of Fourier "Slice" and edge detection with Fast Fourier Transform, allow obtaining both the three-dimensional wavefront map and the depth map in real scenes within a wide range of volumes.
This invention can be useful in any area or application where it is necessary to know the wavefront: terrestrial astronomical observation, ophthalmology,… as well as in those where metrology is required: real scenes, CCD polishing, automotive mechanics,… It applies to the particular case of atmospheric tomography in observations with ELTs (Large Diameter Telescopes: 50 or 100 meters).
