Overview:
Lasers can be used for ...-making instant parts -transmitting data -creating holograms -cutting -guidance |
Coherence:
-sameness in light-coherent light can be measured in nanometers -visible light can be measured around 300 - 800 nanometers -ranges of less than +- 4 nanometers has been achieved -this range can be adjusted with tuning or can be programmed |
Mediums:
-In a vacuum, light has a constant limit unless accelerated by gravity which
proves light is not the cosmic speed limit (about 186,000 miles/sec)-Light can be slowed and accelerated through a prism. -This prism can be of any nature not excluding gravity, atmosphere, and water. -There is an index of refraction based on standards |
Power:
-A number of pass throughs of light in a medium can enhance it's power-The medium can be primed externally at low power |
Holography:
-Layered image patterns can be used to construct objects-The pattern sheets should be marked with the type of laser light used -More power changes the luminousity -A reference beam and object beam create the patterns -Moire patterns may be a side product of imaging -Computers can generate these patterns |
Virtual Imaging:
-A virtual object pattern can be computer generated-An object pattern can be replicated with real objects and a reference beam -Red, Green, and Blue can be converged for a true object |
