3. Conclusion

Some thirty years ago, in the film Goldfinger, the director showed a laser cutting a steel plate to which the famous secret agent James Bond was attached. At the time, the first continuous emission lasers had a power of just a few milliwatts (the first helium-neon laser operated in 1962), far from enough to even mark metal. Many scientists laughed at the time, forgetting all too quickly the rapid and sometimes unexpected progress made by science. Today, industrial lasers cut steel plates with ease, and lasers in research laboratories do even better! So we won't try to predict the future of holography. But we do believe it will exceed the wildest expectations of its users.

However, based on reasonable extrapolations of the technology, we can list the progress we hope to see in the short and medium term. The evolution of industrial holography is essentially conditioned...
