A new optical architecture, based on a double-sideband filter simultaneously applied at the Fourier plane, is proposed for in-line digital holography. The proposed architecture not only allows to remove additional conjugate images at the final object image but also reduces to certain extent deformations that usually appears when using a single-sideband filter. The set-up uses two CCD cameras to simultaneously capture all the needed information, allowing the register of a digital holographic movie.
