Abstract
From the point spread function and wavelength spread, the hologram image resolution and color blur for a one-step rainbow holographic process are analyzed. To achieve a higher image resolution and smaller degree of color blur, we proposed the insertion of a cylindrical lens in a one-step rainbow holographic process. We have shown that higher image resolution and a smaller degree of color blur can be obtained by the cylindrical lens technique. Experimental confirmations of the calculated results are also demonstrated. There is another advantage of the cylindrical lens technique, that is, a higher object beam irradiance, for which it relaxes the power requirement of the coherent source.
