Abstract

In the paper a new concept of digital holographic tomograph (DHT) based on interferometric tomography and digital off-line holography is presented. Capability of registration of microobjects located at different distances from hologram is the basic characteristics of DHT. This feature is used in order to register an object in several views. This is performed by a multiple pass arrangements. However such multipass configuration brings a lot of new issues to be considered including the proper identification of information from sequential pass through object, analysis of the influence of diffraction and others on the object reconstruction. Therefore the extended simulations of reconstruction of amplitude and phase microobjects by means of digital holographic interferometry are performed. The pros and cons for using multipass DHI as the source of data for tomographic reconstruction of amplitude-phase microelements are discussed.
