Resolving starlight: a quantum perspective

M Tsang - Contemporary Physics, 2019 - Taylor & Francis
The wave-particle duality of light introduces two fundamental problems to imaging, namely,
the diffraction limit and the photon shot noise. Quantum information theory can tackle them …

Subdiffraction incoherent optical imaging via spatial-mode demultiplexing

M Tsang - New Journal of Physics, 2017 - iopscience.iop.org
I propose a spatial-mode demultiplexing (SPADE) measurement scheme for the far-field
imaging of spatially incoherent optical sources. For any object too small to be resolved by …

Interferometric superlocalization of two incoherent optical point sources

R Nair, M Tsang - Optics express, 2016 - opg.optica.org
A novel interferometric method–SLIVER (Super Localization by Image inVERsion
interferometry)–is proposed for estimating the separation of two incoherent point sources …

Widefield microscopy with infinite depth of field and enhanced lateral resolution based on an image inverting interferometer

D Weigel, H Babovsky, A Kiessling… - Optics Communications, 2015 - Elsevier
We present an interferometric method to gain a theoretically infinite depth of field.
Simultaneously, this technique yields an enhanced lateral resolution. This can be achieved …

Manipulation of doughnut focal spot by image inverting interferometry

X Hao, C Kuang, Y Li, X Liu - Optics letters, 2012 - opg.optica.org
Based on image inverting interference combined with phase modulation, we theoretically
demonstrate that the doughnut focal spot can readily be manipulated, and either shrinkage …

Two-lens anisotropic image-inversion system for interferometric information processing

W Larson, BEA Saleh - Optics Express, 2021 - opg.optica.org
Interferometric image processing systems based on image inversion normally use multiple
paths with inversion mirrors. Since such systems must meet strict requirements of alignment …

Combination of the resolution enhancing image inversion microscopy with digital holography

D Weigel, T Elsmann, H Babovsky, A Kiessling… - Optics …, 2013 - Elsevier
We propose a method to combine image inversion microscopy (IIM) with digital holography.
By using this technique we are able to avoid some disadvantages of the IIM, like the use of a …

Continuous manipulation of doughnut focal spot in a large scale

X Hao, C Kuang, Y Li, X Liu - Optics Express, 2012 - opg.optica.org
We theoretically demonstrate that the doughnut focal spot can continuously be manipulated
by synthetically using various beam modulation techniques. Comparatively, a more evident …

Imaging properties of different types of microscopes in combination with an image inversion interferometer

D Weigel, H Babovsky, A Kiessling… - Optics Communications, 2014 - Elsevier
Image inversion microscopy enables an increase of the lateral resolution of optical
microscopes. A huge advantage of the method is the possibility to combine it with different …

Contrast reversal confocal microscopy

X Hao, C Kuang, Z Gu, S Li, Y Li, X Liu - Optics Communications, 2013 - Elsevier
We propose a novel method to improve the lateral resolution of a general confocal laser
scanning microscopy (CLSM) by 10–35%, which can be readily realized by manipulating the …
