Abstract

In this proceeding, we present the description of the numerical approach for resolution enhancement, field of view widening and noise reduction in pulse time-domain holography. The approach comprises iterative procedure of the recorded hologram self-extrapolation into wider spatial area, and consecutive ‘self-healing’ of an object. The concept has been proofed on a synthetically generated pulse time-domain holograms. The proposed method is sought after, especially in THz range, where the distance between the object and the hologram lies in the order of several tens of wavelengths, and the detector sizes are usually limited, and with minor modifications can be applied for other THz holographic approaches.
