FIELD: physics.
SUBSTANCE: phase camera has microlenses placed at the focal point of a converging lens, wherein data of the camera which are processed using a combination of "Fourier-section" and a method for image recognition via fast Fourier transform.
EFFECT: three-dimensional map of a wave front, and a real map of the depth of the captured object within a wide range of volumes.
