The laser beam bounces off a first mirror, which is mounted off axis on a stepping motor. Next the beam bounces off a second mirror, also mounted off-axis on a second stepping motor. Under Manual control, the user can adjust the speed of each motor, creating a wide variety of geometric designs. Actual color of beam is red. In the Manual mode, many more patterns can be created by adjusting the speed of rotation of each of the rotating mirrors.
Image size is determined by the distance from the projector to the screen.
Tunnel effects can be produced by passing beams through smoke created by a Roctronics Fogger. Blue-green color shown is produced by Argon gas laser. Such shows are often preprogrammed and played in synchronism to popular music. They are popular for concerts, sales promos, special events, festivals. Call Roctronics for more information.
