    Abstract

    In the paper we will discuss the wide angle capture and display systems applied for digital holographic interferometry (DHI). The static capture system is based on a single camera and an object located at a rotational stage. The holograms are captured sequentially in time during object loading and the phases at a hologram plane are calculated by phase shifting method. The dynamic capture system employs several cameras located around an object and simultaneous capture of several holograms is performed with the frequency of impulse laser applied. For both DHI capture systems the holographic display configuration is proposed. Multiple spatial light modulators aligned in circular configuration are put to work together. In the paper the main requirements for optical reconstruction of resultant interferograms originated from both capture systems are discussed. The results of experiments are presented and analyzed.
