It was some sort of light emission, that much he could see.
For most machines, the raw data is a curve that represents light emissions.
Electromagnetic transmission includes light emissions traveling in a straight line.
It is used to map the physical characteristics of light emission for use in functional systems.
Bioluminescence is the process of light emission in living organisms.
This light emission is based on the nonlinear optical principle.
And just in the last few years, people have observed light emission from these bubbles.
Where potential gradients are used to create excited states that decay by light emission.
Mechanoluminescence is light emission resulting from any mechanical action on a solid.
Only about 75 micrometers thick layer of the gas is responsible for the light emission.
