title: Depth resolved imaging by digital holography with an illumination of constantly changing curvature.
abstract: In this Letter, a single wavelength digital holographic method is proposed to achieve depth resolved imaging by recording a series of holograms in the reflection geometry with an illumination of constantly changing curvature. A proper algorithm is employed to selectively generate the images of the object at different depths, including the phase and the modulus information. Theoretical analysis is supported by a visible light experiment to illustrate the feasibility of the proposed method.
