The scope of this work is to develop a miniature digital holographic interferometry (DHI) system enabling remote measurements of shape and deformation of small 3D objects. Due to the use of digital holography the system does not require holographic plates but uses a simple digital camera for recording of holograms. Object intensity and phase is reconstructed numerically by Fresnel approach and can be applied for monitoring of object changes. In the paper the variety of systems described in literature are presented and analyzed. The configuration of novel digital holographic interferometer is described and the phase analysis method and scaling algorithms are presented. The initial experimental results obtained by means of DHI demonstrator are presented for the case of a small active micro membrane testing. The error analysis and further suggestions toward design of the final version of DHI system are given.
