TOM 10 Frontiers in Optical Metrology

From quantum imaging to quantum reading and pattern recognition by quantum correlations

Ivano Ruo Berchera

INRIM, Italy

The use of quantum states of light, such as entanglement and squeezing, allows surpassing the limitation of conventional measurement essentially increasing the amount information extracted about an object under investigation for a fixed probing energy. While quantum metrology deals with the estimation of an unknown value of a parameters encoded in a state or a physical transformation

(quantum channel), quantum hypothesis testing deals with the discrimination among discrete values characterized beforehand.

We show the coherence properties of a signal can be measured by a Hartmann wavefront sensor in a nonclassical regime. Recasting the detection theory of the classical Hartmann sensor in the sense of quantum tomography enables to measure the coherence function, which is an analogy to the density matrix of mixed quantum states. Two methods were tested for the reconstruction of the coherence matrix from the intensity scan in the nonclassical mode of the Hartmann sensor. The reconstruction was performed in a classic way using the POVM matrix and using data pattern tomography.

TOM 10 Frontiers in Optical Metrology

Stokes CMOS polarimetry limits studied at non-classical polarisation states

Eva Roiková, Štěpán Kunc

Technical University of Liberec, Czech Republic

We present the study of the two polarisation state analysers. The first consists of a polarisation camera with a removable QWP, and the second consists of a non-polarisation camera with a rotating QWP and a stationary linear polariser. The theoretical analysis and experiment focus on studying the influence of polarimeter optical components accuracy and errors such as retardation errors, misalignments and extinction ratio on Stokes parameters precision. This research is a cornerstone to understanding polarisation state analysers limits. We examined laser beams with non-classical polarisation distribution, namely the Poincaré beam and the beam with radial polarisation.

Fabrication influences on a miniaturised stokes polarimeter consisting of stacked nano-optical wire grid polarizer and retarders

Thomas Siefke, Markus Walther, Carsten Stock, Uwe Zeitner

FSU Jena, Germany

The polarization properties of light can be fully controlled with nano-optical wire grid polarizers and artificial birefringent grating structures. We demonstrate an integrated polarimeter based on stacked layers of such elements. However, the optical performance of such elements is fundamentally limited and may be further altered by deviations arising from the fabrication processes. In this contribution we investigate the influences on the polarimetry performance for such a device.
