Im very impressed with the quality given the seeming lack of vibration mitigation. The only hologram I ever made involved working on a basement floor for stability and having to hold my breath and remain motionless during the exposure.
Thanks! Yes, because these are true laser-recorded holograms the fringe pattern is quite high frequency. But the design of the 3D Hologram Printer greatly minimizes the issues and you don't need separate vibration isolation equipment.
