A tilted mirror and L1/H1 ratio above 1.5 balance optical paths for compact, high-quality imaging across wavelength ranges.
A transparent AR housing, camera, and prism optics integrate virtual displays with real surroundings to reduce safety risks.
Moving lens groups and aspherical surfaces support compact variable-magnification imaging with shorter focus travel.
Separate visible and near-infrared paths with dedicated sensors to address chromatic aberration and preserve 4K imaging.
Separate guides, dual rails, and magnet-coil drive limit friction torque and lens tilt in compact zoom camera modules.
Inorganic nanoparticle curing balances prism-sheet refraction with abrasion resistance.
Rotating rhomboidal prisms expand autocollimator aperture coverage, while feedback corrects prism errors for accurate optical alignment.
Internal intermediate imaging positions and reflecting surfaces compact the optical path while limiting scratch and dust impact.
Segmented micro-prisms reproduce multiple floating, sunken, and 3D patterns with white light for safer optical authentication.
Synchronized prism sliding prevents blockage for accurate image stabilization.
This case uses point- and line-like recessed air barriers near gate traces to block stray light and preserve image quality.
