Abstract
Improving the efficiency and expanding the scope of application of lensless optics require increasing its reliability in measuring light fields. The paper examines the complex field generated by a phase object, i.e., a lens. It is shown that reliable phase reconstruction is possible using two or more measurements of the intensity distribution at different distances from the object. A combination of a circular diaphragm and a lens located behind it is used as an object.
