Shack–Hartmann sensor: An instrument that divides an incoming wavefront into multiple subapertures to analyse local tilts and reconstruct the overall phase.

A video of the static fire test showed a large plume of exhaust burning through part of the booster.

A meta-lens array-based Shack-Hartmann wavefront sensor enhances phase measurement by increasing sampling density and angular resolution, advancing optical wavefront sensing with metasurface ...

The The Stratospheric Projectile Entry Experiment on Dynamics (SPEED), a two-stage stratospheric drop test architecture, is ...
