This is old. Think of the advances they have made.
Transmitting HOLOGRAMS.
4) Interferometry using real-time holography
We invented a microscope which removes the image of stationary
objects from a scene, and shows only the moving objects. For example, if one
views a section of living nerve tissue through this microscope, one should be
able to see the slight changes in the nerve as an electrical signal propagates
down the nerve. The microscope uses two-wave mixing between two
coherent laser beams in a photorefractive crystal of BaTiO 3 . One of the
beams (the “image-bearing” beam) passes through the microscopic sample
before it enters the crystal. The other beam (the “reference” beam), which is
considerably more intense, is sent directly into the crystal, as shown in Figure
8. In the absence of any movement or change in the microscopic scene, the
image-bearing beam and the reference beam interfere in the crystal and
create a hologram. The beams then scatter off of this same hologram. The caxis
direction of the crystal is aligned so that the image-bearing beam is
depleted by the interaction. The transmitted portion of the image-bearing
beam is viewed with an eyepiece.

P.S. I grew up in Livermore CA, where the second laboratory was opened. Small town so that was a main employer, lots of my friend’s parents were the scientific types. We called it the rad lab because most work was around radiation. We had crazy mutant sheep being born, and cancer in humans happen after awhile.
