Reconstruction of Signal using Interpolation

Reconstruction of Signal using Interpolation

Signal processing techniques are essential for accurately converting continuous signals to digital formats and vice versa. When a continuous signal is sampled with a period T, the resulting sampled signal exhibits replicas of the original spectrum in the frequency domain, spaced at intervals equal to the sampling frequency. To handle this sampled signal, a zero-order hold method can be applied, which creates a piecewise constant signal by retaining each sample's value until the next sampling...

Summary

This study introduces a novel method for hologram reconstruction, separating object images from unwanted ones using phase-shifted holograms. The technique employs the Hartley transform and phase retrieval for clearer image separation.

Area of Science:

Optics and Photonics
Digital Image Processing

Background:

In-line holography often suffers from overlapping zero-order and conjugate images with the desired object image during reconstruction.
This overlap complicates accurate analysis and interpretation of holographic data.

Purpose of the Study:

To develop a novel method for separating the object image from zero-order and conjugate images in in-line holograms.
To improve the fidelity of reconstructed images in digital holography.

Main Methods:

Utilizing two quadrature phase-shifted holograms.
Applying the Hartley transform to the difference hologram.
Employing a phase retrieval algorithm on the transformed data.

Main Results:
