Automated holographic recording using six-axis robot arm pair

We introduce a novel holographic recording platform employing two laser optics mounted on six- axis robotic arms. These optics can be freely positioned and tilted relative to the holographic substrate, providing complete control over hologram placement, and enabling the recording of arbitrary plane volume gratings. The platform features fiber-based beam delivery and modular beam-shaping optics that produce homogeneous 40mm diameter beams and allow for precise adjustment of beam parameters. We demonstrate the system’s interferometric stability and present initial holograms, highlighting capabilities such as single-substrate multi-patterning. This setup enables rapid prototyping of holographic optical elements and opens avenues for future applications like immersion-free recording schemes for waveguide displays and in-situ characterization after recording.
