Noise resilient real-time phase imaging via undetected light

Josué Ricardo León-Torres, Patrick Hendra, Yugant Mukeshbhai Hadiyal +5 more

Quantum imaging with undetected light has recently emerged as a technique in which quantum correlations and nonlinear interferometry are combined to decouple illumination and detection paths. This approach has been more recently extended and combined with digital phase-shifting holography and off-axis holography to extract both the amplitude and phase information of a sample relying on single-photon interference. Despite these advantages, implementing the technique in real-world scenarios where the observed system is subject to environmental noise and dynamic variations remains challenging. The primary limitation lies in the inability of quantum imaging systems to retrieve object information in real time under high-noise conditions. Here, we experimentally demonstrate real-time amplitude and phase imaging in noisy environments, building upon our previous implementation of quantum off-axis holography. Our results demonstrate real-time imaging at acquisition rates up to 4~Hz, even when the noise level exceeds the signal by an order of magnitude.

Synthetic Off-Axis Quantum Holography with Undetected Light

Sebastian Töpfer, Sergio Tovar-Pérez, Josué R. León Torres +4 more

This work presents synthetic off-axis quantum holography with undetected light, a novel approach to obtain holographic information with a single acquisition. Holography is a vital tool for imaging [1] but is mainly limited to the visible range caused by the availability of efficient detectors. Interesting applications, like identifying molecular signatures and analyzing material properties are excluded, particularly those requiring detection in regions outside the visible spectra of light, for example the mid-infrared [2]. Quantum holography with undetected light (QHUL) was presented in 2022 [3] to give access to these harder-to-detect wavelength regions. However, it is required to do multiple acquisitions to reconstruct the amplitude and phase, preventing the usage in dynamic processes.

Quantum holography with undetected light

Sebastian Töpfer, Marta Gilaberte Basset, Jorge Fuenzalida +3 more

Holography exploits the interference of a light field reflected/transmitted from an object with a reference beam to obtain a reconstruction of the spatial shape of the object. Classical holography techniques have been very successful in diverse areas such as microscopy, manufacturing technology, and basic science. However, detection constraints for wavelengths outside the visible range restrict the applications for imaging and sensing in general. For overcoming these detection limitations, we implement phase-shifting holography with nonclassical states of light, where we exploit quantum interference between two-photon probability amplitudes in a nonlinear interferometer. We demonstrate that it allows retrieving the spatial shape (amplitude and phase) of the photons transmitted/reflected from the object and thus obtaining an image of the object despite those photons are never detected. Moreover, there is no need to use a well-characterized reference beam, since the two-photon scheme already makes use of one of the photons as reference for holography.

Off-axis holographic imaging with undetected light

Josué Ricardo León-Torres, Filip Krajinić, Mohit Kumar +5 more

Quantum imaging with undetected light (QIUL) leverages the quantum correlations of photon pairs generated via spontaneous parametric down-conversion (SPDC) to retrieve both amplitude and phase information of an object. This method enables illumination and detection at distinct wavelength ranges, utilizing advanced detection technology in the visible spectrum while probing the object at an exotic wavelength. Here, we experimentally demonstrate a QIUL technique incorporating Fourier off-axis holography within a hybrid-type induced-coherence nonlinear interferometer. Our approach reconstructs the amplitude and phase information of an object in a single shot using a wide-field configuration, presenting a viable alternative to multi-frame acquisition techniques such as phase-shifting holography.

Off-Axis Holographic Imaging With Undetected Light

Josué Ricardo León-Torres, Filip Krajinić, Mohit Kumar +5 more

Quantum Imaging with Undetected Light (QIUL) leverages the quantum correlations of photon pairs, generated via spontaneous parametric down-conversion (SPDC), to extract both the amplitude and phase information of an object [1]. This process facilitates the simultaneous illumination and detection across a diverse spectral range, harnessing advanced detection technology within the visible spectrum while probing the object at an unconventional wavelength. In this study, we provide an experimental scheme of a QIUL that merges Fourier off-axis holography with a hybrid-type induced-coherence nonlinear interferometer [2], [3], combining a March-Zender and Michelson interferometer to be able to angle-tune the object and reference beams in a wider range of values, and therefore accessing to the full capabilities offered by the Fourier space [4], [5]. Our methodology in a wide-field configuration requires only a single-shot to reconstruct the amplitude and phase data of an object, thus introducing a strong alternative to sequential multi-frame acquisition techniques such as digital phase-shifting holography [6]. Figure 1 shows the image reconstruction process to extract the amplitude and phase information out of the single-photon hologram, a Fast Fourier Transform (FFT) of the hologram reveals the diffraction term containing the object information to be cropped and inverse Fourier transformed to extract a complex image from which the amplitude and phase are retrieved.
