Before CMOS sensors, digital cameras used charge-coupled devices or CCD sensors. This classic sensor design gathers light from the pixels and sends it to an amplifier in order to convert energy from ...

Researchers have developed photonic computing chips that overcome key limitations for a type of neural network known as a photonic spiking neural system. By enabling fast learning and decision making ...

Electrical engineers at Duke University have demonstrated the fastest pyroelectric photodetector to date, which works by absorbing heat generated by incoming light. Capable of capturing light from the ...

For more than a decade, Evan Economo's lab has been using micro-CT machines to scan insect specimens. The resulting X-ray images help researchers study the form and structure of insects—a subfield of ...
