Power-free optical layer system for providing and modulating ambient light for holographic depth, line and projection effects

Abstract

A currentless optical layer system characterized in that it passively absorbs ambient light, guides it within an optical layer assembly, and couples it out again to generate or modulate holographic effects.

Description

Technical field

[0001] The invention relates to currentless optical layer and carrier systems for using ambient light for holographic display, depth, and projection effects. It is particularly intended for holographic displays, transparent display units, depth visualizations, and projection media without an active light source. State of the art

[0002] Holographic display and projection technologies are currently based predominantly on active light sources such as LED backlights, laser sources or projectors.

[0003] These systems require electrical energy, complex controls, and additional installation space and cooling concepts.

[0004] A completely currentless, passive optical layer system that uses or modulates ambient light to support holographic depth or projection effects is not yet known. Technical problem

[0005] The technical problem is to provide or support holographic depth, line, or projection effects without using electrical energy, active light sources, or electronic components. Solution to the task

[0006] The task is solved by a currentless optical layer system that passively absorbs ambient light, guides it within a layered structure, and couples it out again at defined points.

[0007] The system acts as an additional optical layer or carrier layer to support holographic displays and projections. core of the invention

[0008] The core of the invention is a passive optical layer composite which: • absorbs ambient light, • the light is conducted internally, • and is specifically modified or output via defined output structures to create or enhance depth, line, edge or projection effects - completely without current. Constructive features

[0009] The optical layer system includes in particular: 1. a passive light-absorbing structure, 2. an internal light guiding structure within the layered composite, 3. defined extraction or modulation structures, 4. Transparent or translucent carrier materials, 5. A design without an electrical energy source, batteries or LEDs. Application areas

[0010] The layering system is particularly suitable for: • holographic displays, • Depth display and visualization systems, • transparent projection media, • Optical additional layers for display and projection units.
