High resolution table-top coherent diffractive imaging of extended samples
, 2022 Paper IM2E.1We present a table-top coherent diffractive imaging setup based on a laser-driven highorder harmonic source at 68.6 eV that can achieve resolutions of sub-20 nm in an extended field of view of 50 × 50 mm2

Color imaging using a system based on 3 diffractive lenses
Компьютерная оптика, 2023 The possibility of essentially reducing the weight and production cost of computer vision systems has led to the publication of a large number of research works dealing with the development of new imaging systems based on diffractive optics.

Wide Field-of-View Imaging With Wavefront Coded Diffractive Photon Sieves
IEEE Photonics Journal, 2016 We report a demonstration of a wide field-of-view (FOV) imaging with a wavefront coded diffractive photon sieves. In conventional diffractive photon sieves (or other diffractive optical elements), clear imaging can only be achieved within near-zero FOV ...

Rapid sensing of hidden objects and defects using a single-pixel diffractive terahertz sensor
Nature Communications, 2023 Terahertz waves offer advantages for nondestructive detection of hidden objects/defects in materials, as they can penetrate most optically-opaque materials.

The diffractive achromat full spectrum computational imaging with diffractive optics
, 2016 Diffractive optical elements (DOEs) have recently drawn great attention in computational imaging because they can drastically reduce the size and weight of imaging devices compared to their refractive counterparts. However, the inherent strong dispersion

Multi-wavelength optical pickup with diffractive optical elements
, 2022 S.2437-2453A novel, to our knowledge, multi-wavelength diffractive optical pickup is presented. The pickup enables multi-focus imaging and increases the data transfer rate considerably. Parallel reading of two or more memory layers is possible.

Karyotyping human chromosomes by optical and X-ray ptychography methods [PDF]
, 2014 Sorting and identifying chromosomes, a process known as karyotyping, is widely used to detect changes in chromosome shapes and gene positions. In a karyotype the chromosomes are identified by their size and therefore this process can be performed by ...
