Off-axis holographic imaging with undetected light

Area of Science:

• Quantum optics
• Photonics
• Holography

Background:

• Quantum imaging with undetected light (QIUL) utilizes quantum correlations from spontaneous parametric down-conversion (SPDC).
• QIUL allows illumination and detection at different wavelengths, enabling advanced visible-spectrum detectors for exotic wavelength object probing.

Purpose of the Study:

• To experimentally demonstrate a QIUL technique.
• To reconstruct object amplitude and phase information in a single shot.

Main Methods:

• Incorporation of Fourier off-axis holography.
• Utilizing a hybrid-type induced-coherence nonlinear interferometer.
• Wide-field configuration for single-shot acquisition.

Main Results:

• Successful reconstruction of both amplitude and phase information of an object.
• Demonstration of a single-shot wide-field imaging technique.
• Validation of QIUL as an alternative to multi-frame acquisition methods.

Conclusions:

• The demonstrated QIUL technique offers a viable single-shot alternative to traditional multi-frame holographic methods.
• This approach advances quantum imaging capabilities by enabling efficient data acquisition.
• The method has potential applications in various fields requiring detailed object characterization.
