Abstract :
In this study, it is aimed to obtain the real time image of the object, whose off-axis hologram recording is saved on CCD camera, from digital phase hologram. For creating the phase hologram, the phase information of the hologram recording on CCD camera is obtained. When the phase information is obtained, the Fourier transform algorithm and continuous wavelet transform methods are used. Finally, the using methods in this study are compared in terms of obtaining real time image having a high image quality and minimum power loss.
