Paper Abstract

Multifacet holographic optical elements (MFHOE) have interesting applications in different field, such as optical computing, optical connections, structured light for vision system, scanning techniques, security, display, and non-standard problems. In some applications, where very small facets are not necessarily needed, the MFHOE can be obtained by direct holographic recording. This technique, simpler and cheaper than CGH, allows the realization of large-area MFHOE. The minimal facet size is however limited to about 1 mm2. A machine for the automatic recording of large analog MFHOE has been built. Holograms as large as 200 X 300 mm can be recorded. The size of the facets ranges from 1 X 1 mm to 20 X 20 mm. The main components of this robot are two moving arms carrying two phase-stabilized PM-fibers, a moving plate-holder and a fixed mask, which can be a simple window or a complex pattern. This machine is specially designed for the fabrication of a very large light collector, which is the key component of a 4m-wide laser scanning system. This paper presents the principal characteristics of the robot and some examples of holograms that can be realized with this machine.
