Compact vortex wavefront coding camera

Computational Imaging V, 2020
We experimentally design, construct and test a compact optical system featuring a vortex diffractive waveplate placed in the aperture stop of the lens system. The wavefront coding camera diffracts polarized coherent illumination in the system's focal plane and reduces the peak intensity of the beam by two orders of magnitude while simultaneously ...

Spatial coding with curved wavefronts

IEEE Ultrasonics Symposium, 2004, 2005
Curved wavefronts of unfocused beams can be viewed as spatial codes that can be decoded to produce high quality images. The decoding process can be performed by spatial matched or Wiener filtering methods that are a generalization of synthetic receive processing for large apertures rather than small elements.

Wavefront coding for visual optics

Third International Conference on Applications of Optics and Photonics, 2017
Wavefront coding (WFC) enables the depth of field of incoherent optical systems to be extended. This method involves a cubic-phase plate in the system yielding a blurred image nearly invariant to defocus. In visual optics there is a big interest in improving solutions for two different problems: Presbyopia correction and high resolution retinal images ...

Applications of wavefront coded imaging

SPIE Proceedings, 2004
Imaging systems using aspheric imaging lenses with complementary computation can deliver performance unobtainable in conventional imaging systems. These new imaging systems, termed Wavefront coded imaging systems, use specialized optics to capture a coded image of the scene.
