Working Principle of 3D Stereoscopic Film

The essence of 3D stereoscopic film is to convert two-dimensional patterns into three-dimensional structures or stereoscopic visual effects.There are two common implementation paths:

1. Grayscale Exposure Molding(Structural 3D)

This is the most core method in industry and is closely related to"grayscale film".

Basic logic:Different areas on the film have different light transmittance(grayscale), During exposure,different positions receive different light energies, Photoresist or photosensitive materials undergo different degrees of reaction(dissolution or curing)

Final result:→ Form structures of different heights(Z-axis)on the material surface

Can realize:Slopes, Curved surfaces,Microlenses, Step structures,

That is,"use one film and one exposure to make a 3D structure".

2. Parallax/Optical Imaging(Visual 3D)

It is more used in visual effects or anti-counterfeiting fields.

Implementation methods include:Lenticular Lens Array, Interlaced Image,Multi-view Coding,

The principle is: Different images are seen from different angles,The human eye forms a"three-dimensional sense"or dynamic effect,

Common effects: Naked-eye 3D,Dynamic switching images(flip,animation),Depth of field effect,

3. Multi-layer Superposition Technology

Through:

 Multi-layer film alignment,Or multiple exposures,

Form more complex three-dimensional structures or optical effects.

Main Features of 3D Stereoscopic Film

1. Capable of Realizing Three-dimensional Structures or Stereoscopic Vision

This is the greatest value different from traditional two-dimensional films:

 Structural type:Real height(micron level),Visual type:Spatial sense/dynamic effect

2. High-precision Microstructure Capability

 Micron or even submicron level control,Suitable for precision optics and micro-nano processing

3. High Process Integration

Especially in grayscale processes:Single exposure replaces multiple processes,Reduces alignment errors

4. High Design Freedom

Can design:Non-linear curved surfaces,Optical functional structures,Dynamic visual patterns

5. High Requirements for Equipment and Processes

Need to cooperate with:High-precision exposure equipment, Stable light source,Precise material response control,

Otherwise,it is easy to appear: Height distortion,Stereoscopic effect deviation.

6. Can be Combined with Multiple Processes

For example:Photolithography+Electroforming(making molds),Injection molding replication(mass production of optical structures)

,UV Nanoimprint.
