A thin Maxwellian‐view VR near‐eye display based on a holographic optical element (HOE) is presented. Integrating the HOE with the display panel eliminates the structural gap, achieving an 8‐mm internal spacing. Accommodation‐independent image sharpness is experimentally verified over a 0‐ to 3.3‐D range, mitigating the vergence–accommodation conflict.

ꟻLIP‐Based Perceptual Optimization for Subpixel Rendering Filters
We propose a two‐stage subpixel rendering framework combining MMSE‐based initialization and ꟻLIP‐guided perceptual optimization. The kernel is refined by minimizing the mean ꟻLIP error using a Nelder‐Mead optimizer to reduce perceptual distortion beyond RGB‐based methods.

Adaptive Display White Point Under Various Ambient Conditions. Part 2: Dual Illumination
This study was designed to investigate how an adaptive display white point should be adjusted under different foreground‐background illumination conditions. It was found that the background illumination had a more significant effect. ABSTRACT Adaptive displays are designed to enhance the user viewing experience by dynamically responding to ambient ...

Optical Skyrmions with Tunable or Reconfigurable Topology Using Spin‐Decoupled Metaoptics
The work introduces advanced optical elements capable of generating and dynamically reconfiguring complex light patterns known as optical skyrmions. By precisely shaping light polarization at the nanoscale, a single engineered metasurface can generate and manipulate robust and tunable polarization textures in an efficient and scalable way.

Deterministic Fiber‐Optic Spectral Engineering Enables Three‐Color Multiplexed Two‐Photon Microscopy
A simulation‐guided spectral‐engineering framework maps the nonlinear parameter space of a fiber laser platform to identify balanced three‐band excitation states. The resulting 960, 1080, and 1175 nm femtosecond pulses deliver nJ‐level energies for low‐cross‐talk chromatically multiplexed two‐photon microscopy.
