FACE-ing the future of single-pixel complex-field microscopy beyond the visible spectrum

Area of Science:

• Optical Imaging
• Spectroscopy
• Photonics

Background:

• Single-pixel imaging (SPI) offers unique advantages for spectral regions where conventional sensors struggle, like the near-infrared spectrum.
• Existing SPI techniques and their complex-field variants are limited by speed and throughput, restricting real-time applications.

Purpose of the Study:

• To introduce and evaluate the frequency-comb acousto-optic coherent encoding (FACE) approach for overcoming SPI limitations.
• To demonstrate the potential of FACE for real-time complex-field microscopy and advanced optical imaging.

Main Methods:

• Development and application of the frequency-comb acousto-optic coherent encoding (FACE) technique.
• Proof-of-concept demonstrations in real-time complex-field microscopy.

Main Results:

• FACE significantly enhances the space-bandwidth-time product for SPI, addressing critical speed and throughput bottlenecks.
• Demonstrated versatility and effectiveness of FACE in real-time complex-field microscopy applications.

Conclusions:

• FACE represents a significant advancement in overcoming SPI limitations, enabling real-time imaging beyond the visible spectrum.
• The technology holds transformative potential for optical imaging, with future directions focused on scalability.
