A spectral-holography application called spectral-decomposition holography forms a recorded image according to optical path length. In this method all wavelength components of a broad-spectrum source simultaneously backlight a nonscattering binary-phase object. A spectral hologram is thus recorded. Subsequent computer processing recovers temporally discriminated images.
