Design, Analysis, and Manufacturing of Diffractive Achromatic Optical Systems
MicromachinesThe increasing resolution requirements of imaging optical systems must be satisfied by expanding the aperture of the optical system according to Rayleigh’s criterion, and larger apertures of conventional refractive/reflective optics place a greater ...

Broadband lightweight flat lenses for longwave-infrared imaging
, 2019 We experimentally demonstrate imaging in the longwave-infrared (LWIR) spectral band (8um to 12um) using a single polymer flat lens based upon multi-level diffractive optics.

Compact achromatic optical Fourier transform system using geometric-phase lenses
JPhys PhotonicsIn this work we present a new configuration to achieve an achromatic all-optical Fourier transform (FT) using two blazed diffractive lenses and one non-dispersive lens.

OpticsStandard endoscopy of vocal folds is in general limited to two-dimensional imaging. Laser-based 3D imaging offers not only absolute measurements but also the possibility of assessing all three spatial directions. However, due to human inter-individuality,

Linearization of an annular image by using a diffractive optic [PDF]
The goal for this project is to develop the algorithms for fracturing the zones defined by the mapping transformation, and to actually produce the binary optic in an appropriate setup.
