New Imaging Technique Accurately Estimates Motion of Individual Objects
Since the advent of photography in the mid-19
th century, imaging technology has certainly come a long way.

Today, several sophisticated cameras meant for challenging applications depend on mechanisms that are significantly different from those seen in consumer-oriented devices. One of these advanced cameras uses the so-called “single-photon imaging,” which can yield highly superior results in fast dynamic scenes and dark conditions. But it is not known how this single-photon imaging is different from traditional imaging.
When capturing an image with a standard CMOS camera, similar to the ones used on smartphones, the camera sensor is exposed to a huge influx of photons at the time of a predefined exposure time. Within the sensor grid, every pixel produces an analog value that relies on the number of photons that strike that specific pixel during the exposure.
Photocatalyst Discovered by Japanese Researchers
The current COVID-19 pandemic has thrown a spotlight on a discovery made by Japanese researchers half a century ago: photocatalyst technology.
Photocatalysts are materials that induce a chemical reaction under photoirradiation. Titanium dioxide, the most widely known, causes strong oxidation when exposed to light. Photocatalyst technology leverages this phenomenon to decompose harmful or odor-causing substances into materials like water or carbon dioxide.
Fujishima Akira, the former president of the Tokyo University of Science, was studying for his PhD at the University of Tokyo when he made this discovery. In 1972, after finding that titanium dioxide oxidizes in water when exposed to strong light, Fujishima published a paper on the photocatalytic reaction in the influential British scientific journal

Imaging technology has come a long way since the beginning of photography in the mid-19th century. Now, many state-of-the-art cameras for demanding applications rely on mechanisms that are considerably different from those in consumer-oriented devices. One of these cameras employs what is known as single-photon imaging, which can produce vastly superior results in dark conditions and fast dynamic scenes. But how does single-photon imaging differ from conventional imaging?
