Modern cameras typically use an array of millions of detector pixels to capture images. By
contrast, single-pixel cameras use a sequence of mask patterns to filter the scene along with …

The production of pairs of entangled photons simply by focusing a laser beam onto a crystal
with a nonlinear optical response was used to test quantum mechanics and to open new …

Computational ghost imaging, in which an image is retrieved from a known patterned field
that illuminates an object and the total transmitted intensity therefrom, has seen great …

Ghost imaging uses optical correlations to enable an alternative and intriguing image
acquisition technique: even though information from either one of the detectors used for the …

In this Letter we report a demonstration of electron ghost imaging. A digital micromirror
device directly modulates the photocathode drive laser to control the transverse distribution …

Different optical imaging techniques are based on different characteristics of light. By
controlling the abrupt phase discontinuities with different polarized incident light, a …

Terahertz (THz) spectroscopy systems are widely employed to retrieve the chemical and
material composition of a sample. This is single-handedly the most important driving …

Since the quality of underwater classical optical imaging is constrained by the absorptive
and scattering nature for underwater environment, it is a challenging task to obtain long …

X-ray “ghost” imaging has drawn great attention for its potential to obtain images with a high
resolution and lower radiation dose in medical diagnosis, even with only a single-pixel …

Imaging with single-pixel detectors becomes attractive in many applications where pixelated
detectors are not available or cannot work. Based on a correlation between the probing …
