Abstract:
Single photon-level imaging at 1550 nanometers is a key driver for crucial advancements in the next-generation laser detection technology. This cutting-edge approach plays a vital role in space ranging, target recognition, and three-dimensional remote sensing. However, it has faced severe challenges such as insufficient noise-tolerant performance. Here, we introduced noise-tolerant correlated coincidence imaging (CCI) based on supercorrelated light (SCL). The light source, generated through nonlinear interaction between a pulsed laser and a photonic crystal fiber, exhibits a broader power-law photon number probability distribution and extremely strong photon correlation [with second-order correlation function g(2)(0) up to 18,166]. Our noise-tolerant CCI can resist random environmental noise up to 100,000 times stronger than the echo signal photons. SCL offers an exceptionally strong noise tolerance for single photon-level imaging in extreme environments with intense noise, paving the way for the future development of extremely sensitive light detection.

Phase Contrast and Differential Interference Contrast Microscopy
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...
