Reflector shaping by optimization of wavefront shapes
Antennas and Propagation Society Symposium 1991 Digest, 2002The shaping of reflector antennas has generally been done by solving a system of partial differential equations (PDEs) which describe the ray tracking system. The technique has been very successful in many cases but has some difficulties with existence and uniqueness questions due to the PDE formulation.

Frontiers in Optics + Laser Science 2024 (FiO, LS)
This talk introduces neural wavefront shaping (NeuWS), a guidestar-free approach for imaging through optical aberrations. NeuWS integrates maximum likelihood estimation, measurement modulation, and neural signal representations to reconstruct diffraction-limited images through static/dynamic scattering media.

Tailoring complex wavefront of scattered light via wavefront shaping
Journal of Optics, 2020Abstract Tailoring complex wavefront is crucial for controlling the propagation and interference of light, but is quite challenging for optical systems that suffers random scattering. Here, we show that wavefront shaping can be used for tailoring complex wavefront on the target plane with phase-only control on the incident plane.

Deformable mirror for wavefront shaping of infrared radiation
Optics Letters, 2018We present proof-of-principle results on terahertz wavefront shaping by means of a deformable mirror (DM). The DM is based on a reflective gold-coated steel membrane pushed by 35 powerful stepper actuators to enable a surface deformation of up to 1 mm out of equilibrium.

Flexible intensity and wavefront shaping with freeform optics
Optics LettersSimultaneously shaping both the luminous intensity and the wavefront of light with freeform optics holds significant potential across numerous applications. However, flexible intensity and wavefront shaping (e.g., generating a predefined intensity with an engineered freeform wavefront) in tilted geometries remains an unresolved problem.
