Analog Modulation

What is Analog Modulation?

In the show laser industry 'analog modulation' defines the ability of a laser source to "dim" the output power of the laser beam, which means that the output power can be adjusted without stepping. Thus, it is possible to display up to 16,7 million different shades of color with multi color laser systems (systems with more than one laser source color). Depending on the technology of the laser source, brightness can be controlled linearly to a great extent. Thereby mixed colors can be created specificly.
For professional laser shows, only laser systems with full analog color modulation are used.

What is TTL Modulation?

Counterpart of analog modulation is TTL-modulation (abbreviation for: Transistor-Transistor Logic -> this means: on/off only).

Can I use TTL Modulation with an analog system?

It does not damage an analog laser device, if it is triggered with a TTL signal (or the other way round).
A TTL RGB laser can only display 7 colors and no fading effects via analog signal are possible.

See this video for the differences between TTL and analog modulation
