It is possible to make holograms of much less stable objects by using a pulsed laser which produces a large amount of energy in a very short time (μs or less). [7] These systems have been used to produce holograms of live people. A holographic portrait of Dennis Gabor was produced in 1971 using a pulsed ruby laser. [1]: Figure 4.5, p44 [8]
In principle, it is possible to make a hologram for any wave. Electron holography is the application of holography techniques to electron waves rather than light waves. Electron holography was invented by Dennis Gabor to improve the resolution and avoid the aberrations of the transmission electron microscope.
It involves generating holographic interference patterns. A computer-generated hologram can be displayed on a dynamic holographic display, or it can be printed onto a mask or film using lithography. [1] When a hologram is printed onto a mask or film, it is then illuminated by a coherent light source to display the holographic images.
"We can think about this image like a 3D-printed object," said BYU assistant prof and lead author Daniel Smalley. Researchers create 'true' 3D holograms by trapping particles [Video] Skip to main ...
Theories of holographic consciousness have also been proposed as a potential explanation for capabilities such as the brain's capacity to retain memories despite extensive damage, [9] the human ability to rapidly discern and integrate large amounts of related data, [10] and a number of documented phenomena which indicate non-locality as a ...
Other studies have shown the correlation between more advanced cognitive function and homeothermy. Taking holographic brain models into account, this temperature regulation would reduce distortion of the signal waves, an important condition for holographic systems. [11] See: Computation approach in terms of holographic codes and processing. [33]
Another related feature is the holographic superposition—when illuminated together (placed side by side), two holograms can generate a superposition of the corresponding two 3D objects. Superposition of objects can also be made by imprinting the images of the two (or more) 3D objects on the same holographic film.
