Multi-plane light converters (MPLCs) are an emerging class of optical devices capable of
converting a set of input spatial light modes to a new target set of output modes. This …

Historically, the resolution of optical imaging systems was dictated by diffraction, and the
Rayleigh criterion was long considered an unsurpassable limit. In superresolution …

The resolution of optical imaging devices is ultimately limited by the diffraction of light. To
circumvent this limit, modern superresolution microscopy techniques employ active …

The need to observe objects that are smaller than the diffraction limit has led to the
development of various superresolution techniques. However, most such techniques require …

Much of our progress in understanding microscale biology has been powered by advances
in microscopy. For instance, super-resolution microscopes allow the observation of …

We establish fundamental bounds on subwavelength resolution for the radar ranging
problem,“superradar.” Information-theoretical metrics are applied to probe the resolution …

Quantum Fisher information and signal-to-noise ratio bounds are derived for the estimation
of moments of general partially coherent objects. Under an asymptotic analysis in the sub …

In a previous paper [M. Tsang, Phys. Rev. A 99, 012305 (2019) 2469-9926
10.1103/PhysRevA. 99.012305], I proposed a quantum limit to the estimation of object …

The optical microscopy image plays an important role in scientific research through the
direct visualization of the nanoworld, where the imaging mechanism is described as the …

A widely tested approach to overcoming the diffraction limit in microscopy without disturbing
the sample relies on substituting widefield sample illumination with a structured light beam …
