Basic Operation

The basic operation of a laser tag system can be found on Wikipedia.

“Laser tag is a team or individual sport or recreational activity where players attempt to score points by tagging targets, typically with a hand-held infrared-emitting targeting device.”

The two basic parts of a laser tag system are (1) a shooting element and (2) a target.

The laser tag system is a simple optical communications link. The shooting element is a modulated LED and the target is a photodetector.

Basic operation of the shooting element:

  • Send a known signal

Basic operation of the target:

  • Determine if the target was hit by a shooting element (i.e. the signal is not just noise)
  • Determine the player by interpreting the signal sent

Now that we know the basic way that the system works we need to determine the basic specifications of the design.

  1. Determine what signal is sent for each player:: There are a variety of different methods to send a signal over an optical link. In this project we are going to use a very simple approach and assign each player a specific modulation frequency.
  2. Determine the number of players: We are arbitrarily choosing to have 10 players.
  3. Determine the frequency of each player: There are several factors that affect the frequencies that we use like:

* The
