Abstract :
The method to reduce speckles in a reconstructed image of a digital hologram is proposed. The size and position of the speckles are changed according to both the wavelengths to be recorded and the distances from the object the hologram. The superposition of the reconstructed images recorded with different wavelength/ distance holograms gives the image with reduced speckles
