Diffractive optical elements (DOEs) are flat or hybrid microstructured surfaces that shape light through diffraction rather than refraction. By sculpting surface relief or embedding subwavelength ...

The transmission of optical information through random scattering media is a major challenge in optics, biomedical imaging, telecommunications and remote sensing. When light passes through a turbid or ...

Diffractive optics harness microscale surface relief patterns to sculpt optical wavefronts through diffraction, offering compact, lightweight alternatives to conventional refractive lenses. Recent ...

A depth-compensated diffractive optical element photoacoustic microscope enables more uniform photoacoustic imaging across tissue depths.
