A nanowire diode with a built-in electron trap senses, denoises, and classifies images without separate processing hardware, mimicking the retina and opening a path to smarter edge computing.

Both image photodetector arrays and retinas are pixelated sensors that dynamically extract various features from the visual scene—e.g., color, brightness, and contrast—before transmitting electrical ...

Imaging technology has transformed how we observe the universe—from mapping distant galaxies with radio telescope arrays to unlocking microscopic details inside living cells. Yet despite decades of ...

Canon's new SPAD sensors work by amplifying a single photon that enters the sensor's pixels into large amounts of electrical energy pulses. This allows the camera to see objects in areas with small ...

Modern electronic devices often have at least a few analog rails in their power profile. This is especially applicable in consumer electronics, automotive, medicine, and smart home devices. Building ...

A new generation of CMOS image sensors can exploit all the image data to perceive a scene, understand the situation, and intervene by embedding artificial intelligence (AI) in the sensor. CEA-Leti ...

The new sensor is more light-sensitive, reproduces colours more accurately and offers significantly higher resolution than conventional silicon sensors. (Nanowerk News) Image sensors are built into ...

Thin-film technology: One of the two perovskite-based sensor prototypes that the researchers have used to demonstrate that the technology can be successfully miniaturized. Taking better photos with ...

The expanding use and importance of image sensors in safety-critical applications such as automotive and medical devices has transformed noise from an annoyance into a life-threatening problem that ...
