<p>The invention relates to a method for writing holographic pixels in a holographic recordable film (3), comprising a photo component that can be changed photochemically and/or photophysically by exposure, wherein the holographic recordable film (3) is positioned above a reflection master (4), wherein a primary light beam (P) is directed at the holographic recordable film (3), wherein the primary light beam (P) penetrates the holographic recordable film (3) and is reflected by the reflection master (4) to form a reflection light beam (R). The primary light beam (P) and the reflection light beam (R) interfere in the holographic recordable film (3) within an interference zone (10) and change the photo component in the interference zone to form the holographic pixel. The method is characterized in that a transmission hologram (6) is arranged between the holographic recordable film (3) and the reflection master (4) and that the transmission hologram (6) diffracts the primary light beam (P) and/or the reflection light beam (R) with the proviso that the interference zone (10) has a larger lateral surface area, in relation to the directions orthogonal to the surface normal for the holographic recordable film (3), than in the absence of the transmission hologram (6).</p> |
