What and how scanners work

How Scanners Work

• Scanners operate using rotating mirrors mounted on motors to direct light in specific directions.
• They create effects like dynamic movement, color changes, and pattern projections by using components such as color wheels, gobo wheels, or LED modules.
• The light source, often an LED or high-intensity discharge lamp, is reflected off the mirror to produce vibrant and versatile visuals.

Applications of Scanners

• Commonly found in nightclubs, discos, and theater performances, scanners excel at creating high-energy effects.
• They are also used for atmospheric background lighting, adding depth and ambiance to events or venues.

Key Features of Scanners

1. Color Options:
   • Scanners come equipped with color wheels or LED modules to produce a wide range of colors.
2. Patterns and Effects:
   • Many scanners include gobo wheels for projecting patterns and stroboscope functions for pulsing or flashing effects.
3. Speed and Precision:
   • Scanners are faster than moving head lights because only the mirror moves, not the entire fixture.

Types of Scanners

• Standard Scanners: Feature a flat mirror for straightforward light direction.
• Roller Scanners: Use a multi-faceted mirror that rotates on its axis, creating unique and eye-catching effects.

Scanners vs. Moving Heads

• Speed: Scanners are quicker, as only the mirror moves.
• Range of Movement: Moving heads have a wider movement range since the entire fixture can pan and tilt.
• Application: Scanners are ideal for fast-paced environments, while moving heads excel in situations requiring broader coverage or complex movements.

Controlling Scanners

• Automatic Mode: Scanners can run pre-programmed lighting sequences.
• Sound Activation: Scanners can synchronize with music, responding to beats for dynamic effects.
• DMX Control: For advanced and precise lighting designs, scanners can be operated through DMX controllers, allowing for full customization.
