The first transformation deals with propagating of waves from the object plane to the lens (in order to create synthetic datasets for testing).
In order to test the algorithms we use a single test object plane to generate synthetic measured wavefronts at [U.
One way to deal with this is compute the expected initial phase for each angle at each point in the object plane but this would require foreknowledge of the optical path between the illuminator and each point.
This paper presents a generic method of calculating accurate horizontal and vertical object distances from digital images taken with any digital camera and lens combination, where the object plane is parallel to the image plane or tilted in the vertical plane.
This paper presents a general solution for measuring distances that can be applied to experiments using any consumer or professional digital camera in an experiment where the image plane is at any vertical tilt angle to the object plane.
where O is the object dimension (in mm), I is the image dimension (in mm), D is the distance from the image plane to the object plane (in mm) and f is the focal length of the lens used (in mm).
