Laser art: Laser Lumia and analog optical projection
Laser Lumia creates changing light patterns through the interaction of a laser beam, refractive materials and movement. Broken Composers explore optical projection in installations and live audiovisual performance.
Broken Composers’ optical practice: Laser Lumia, manually controlled projection and the distinction between the broader technique and Kirill Rave’s patent.
Physical optics
Unlike a pre-rendered video image, an optical pattern emerges from light passing through physical materials. Changes in geometry, rotation or positioning change the projection. Laser Meadows brings Laser Lumia patterns and music into a landscape through which visitors move.
Lumia Modul combines manually controlled analog laser projection with live music made from steel percussion, flutes and strings. Light is part of the performance rather than a conventional video surface.
The specific patented arrangement
Kirill Rave individually developed the method described in Russian patent RU2705182C1, published in 2019. The patent concerns a specific projection arrangement using rotating refractive objects. It does not cover Laser Lumia as a whole.
The About page links to the original patent and explains this arrangement. Umbra explores a different relationship between light and sound: objects interrupting a laser plane trigger musical notes.
