We present the first 1Mpixel SPAD camera ever reported. The camera features 3.8 ns time
gating and 24kfps frame rate; it was fabricated in 180nm CIS technology. Two pixels have …

Ghost imaging, based on single-pixel detection and multiple pattern illumination, is a crucial
investigative tool in difficult-to-access wavelength regions. In the terahertz domain, where …

Optical imaging techniques, such as light detection and ranging (LiDAR), are essential tools
in remote sensing, robotic vision, and autonomous driving. However, the presence of …

Optical imaging in scattering media is important to many fields but remains challenging.
Recent methods have focused on imaging through thin scattering layers or thicker scattering …

High-resolution single-photon imaging remains a big challenge due to the complex
hardware manufacturing craft and noise disturbances. Here, we introduce deep learning into …

This work reviews physical concepts, technologies and applications of time-domain diffuse
optics based on time-gated single-photon detection. This particular photon detection …

Spatial correlations between two photons are the key resource in realising many quantum
imaging schemes. Measurement of the bi-photon correlation map is typically performed …

The dependent scattering effect (DSE), which arises from the wave nature of
electromagnetic radiation, is a critical mechanism affecting the radiative properties of …

Cameras with extreme speeds are enabling technologies in both fundamental and applied
sciences. However, existing ultrafast cameras are incapable of coping with extended three …

Current terahertz (THz) spectroscopy techniques only use the coherent light beam for
spectral imaging. In the presence of electromagnetic scattering, however, the scattering …
