Laser
Light Amplification by Stimulated Emission of Radiation.The laser is
an intense light source. Light from a laser is all the same frequency,
unlike the output of an incandescent bulb. Laser light is typically
coherent and has a high energy density.
Laser Diode
A gallium-arsenide semiconductor type of laser connected to a
power source to generate a laser beam. This laser type is a compact
source of coherent light.
Light Emitting Diode (LED)
A low power electronic light source commonly used as an indicator
light. It uses less power than an incandescent light bulb but more
than a Liquid Crystal Display (LCD).
Liquid Crystal Display (LCD)
A display that uses liquid crystal sealed between two glass plates.
The crystals are excited by precise electrical charges, causing them
to reflect light outside according to their bias. They use little
electricity and react relatively quickly. They require external light to
reflect their information to the user.
MIL
1 mil = 1 thousandth of an inch.
