Glossary
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

communicate with each other and establish a connection.
