Recording/Reproducing/Erasing Using Optical Interference Patterns TRIZ Cases
- Spatially Varying Hologram Writing With Toric Wavefront Conditioning
Toric optics and mirrors condition writing beams for spatially varying holograms, helping HMD eye tracking overcome eyelid and eyelash obstructions.
- Holographic Recording Media Curing to Reduce 3D Birefringence
A staged curing process for holographic recording media limits birefringence and polarization changes to sustain light-guiding efficiency.
- Volume Hologram Element Continuous Fringes Reduce Optical Loss
Continuous interference fringes in a segmented volume hologram element eliminate exposure overlap, reducing optical loss and improving diffraction efficiency.
- Holographic Recording Medium Overlap Multiplexing
A holographic recording method multiplexes interference fringes by overlapping neighboring pixels on the medium.
- Holographic Optical Elements with Integrated Incoupler and Outcoupler
Integrating incoupler and outcoupler holograms in one medium eliminates spatial alignment of separate components, reducing assembly complexity.
- Holographic Storage Write Session Management
Postponing the fixing step until capacity is fully utilized minimizes storage capacity loss by keeping write sessions open for appending data.
