Abstract

We investigate the fundamental limits for object axial position estimation using the quantum Fisher information. Placing an intensity position detector into a proper place out of the image plane enables detection attaining those limits.

Quantum limit to subdiffraction incoherent optical imaging

Mankei Tsang

The problem of finding the fundamental resolution of an optical system can be cast in terms of a quantum estimation problem. Here an upper bound on the quantum Fisher Information for the moments of an arbitrary subdiffraction object is derived, establishing a criterion of resolution for far-field incoherent imaging.

Attaining quantum limited precision of localizing an object in passive imaging

Aqil Sajjad, Michael R. Grace, Quntao Zhuang +1 more

We investigate our ability to determine the mean position, or centroid, of a linear array of equally bright incoherent point sources of light whose continuum limit is the problem of estimating the center of a uniformly radiating object. We consider two receivers, an image-plane ideal direct-detection imager and a receiver that employs Hermite-Gaussian (HG) spatial-mode demultiplexing in the image plane, prior to shot-noise-limited photon detection. We compare the Fisher information (FI) for estimating the centroid achieved by these two receivers, which quantifies the information-accrual rate per photon, and compare those with the quantum Fisher information (QFI): the maximum attainable FI by any choice of measurement on the collected light allowed by physics. We find that focal-plane direct imaging is strictly suboptimal, although not by a large margin. We also find that not only is the HG mode sorter, which is the optimal measurement for estimating the separation between point sources (or the length of a line object), suboptimal, but it performs worse than direct imaging. We study the scaling behavior of the QFI and direct imaging's FI for a continuous uniformly bright object in terms of its length and find that both are inversely proportional to the object's length when it is sufficiently larger than the Rayleigh length. Finally, we propose a two-stage adaptive modal receiver design that attains the QFI for centroid estimation.

We determine the general limit to the maximum achievable sensitivity in the estimation of a parameter from the information contained in an optical image in the presence of quantum noise, either coherent or squeezed.

We derive quantum limits and optimal measurements for arbitrary hypothesis tests between incoherent, diffraction-limited objects, enabling discrimination of an order of magnitude more objects than direct imaging.

Intensity-Based Axial Localization at the Quantum Limit

Jaroslav Řeháček, Martin Paùr, B. Stoklasa +3 more

We derive fundamental precision bounds for single-point axial localization. For Gaussian beams, this ultimate limit can be achieved with a single intensity scan, provided the camera is placed at one of two optimal transverse detection planes. Hence, for axial localization there is no need of more complicated detection schemes. The theory is verified with an experimental demonstration of axial resolution 3 orders of magnitude below the classical depth of focus.
