Deep Underground Science and Engineering, EarlyView.Aluminum‐enhanced afterburning renders AE explosives more hazardous than conventional ones. Corrugated steel linings reduce far‐field AE blast overpressure by ~50% through wave reflection and dissipation. The developed model accurately predicts peak pressure (<10% error) and arrival time (<3% error), supporting protective design.

Performance Comparison of Wavefront-Sensorless Adaptive Optics Systems by Using of the Focal Plane
International Journal of Optics, 2015 The correction capability and the convergence speed of the wavefront-sensorless adaptive optics (AO) system are compared based on two different system control algorithms, which both use the information of focal plane.

Bio‐inspired nanophotonics: Structural color, chirality, and resonance metasurfaces
InfoMat, EarlyView.A butterfly‐wing‐inspired anisotropic plasmonic flatband resonant metasurface. Insets, photo of the butterfly, Sasakia charonda, and the SEM image of its wing scale (above); the SEM image of the metasurface (below). Abstract The dazzling colors of butterfly wings and hummingbird feathers are not painted with pigments, but crafted by nature's invisible ...

Focal plane wavefront sensor achromatization : The multireference self-coherent camera
, 2016 High contrast imaging and spectroscopy provide unique constraints for exoplanet formation models as well as for planetary atmosphere models. But this can be challenging because of the planet-to-star small angular separation and high flux ratio. Recently,

Wavefront sensorless adaptive optics for large aberrations
Optics Letters, 2006 In some adaptive optics systems the aberration is determined not by using a wavefront sensor but by sequential optimization of the adaptive correction element. Efficient schemes for the control of such systems are essential if they are to be effective.

Journal of the Society for Information Display, EarlyView.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.

Laser-controlled adaptive optic for beam quality enhancement in a multipass thin disk amplifier
, 2018 We devise a laser-controlled adaptive optical element which operates intracavity under high intensity radiation. This element substitutes a conventional mechanically deformable mirror and is free of critical heat-sensitive components and electronics. The
