Holographic Optical Components TRIZ Cases
- Holographic Grating Vectors for Near-Eye Display Uniformity
Non-uniformly spaced grating vectors modulate diffraction angles to mitigate angular harmonic sight lines and prevent corn row artifacts in near-eye displays.
- Holographic Display Spatial Filter for Lattice Spot Separation
A spatial filter with pinholes and color filters separates holographic images from lattice spots, expanding the viewing window by blocking diffraction noise.
- Phase Light Modulator Iterative Wave-Propagation Control
An iterative wave-propagation loop maps reconstruction fields to modulation fields, eliminating image artifacts without discarding energy.
- Interferometer Compensation Device for Moving Specimen Measurement
A compensation device adjusts optical path length differences in an interferometer to measure surfaces of moving test objects.
- Digital Holographic Imaging Limiter for Aliasing Suppression
A digital holographic imaging apparatus uses a limiter to constrain spatial frequencies and incident angles on the image sensor.
- Hologram Exposure Machine Camera Alignment
Camera optically captures exposure area to monitor beam position and intensity, reducing manual adjustment time.
- Holographic Film Shearing for Dynamic Eye Tracking
Segmented holograms share a reference beam while a shearing mechanism shifts diffraction angles based on detected pupil position, expanding viewing range.
- Reflective Viewing Window Module for Hologram Displays
A viewing window control module uses reflective optical systems to form and expand hologram display windows.
- Holographic Display Phase Coding Iterative Fourier Algorithm
A holographic display system uses an iterative Fourier transformation algorithm to compute phase values on a spatial light modulator.
- Liquid Crystal Hologram Element for Thin Optical Pattern Projection
A liquid crystal hologram element diffracts transmitted light into multiple directions to project optical patterns.
