Canon Develops Sensor that Can Shoot Full Color Photos in the Dark

Posted by in categories: computing, electronics

It is the highest resolution sensor of its type ever made.


Canon has developed an image sensor that is capable of capturing high-quality color photography even in the dark. The company says that it will be able to shoot clear photos even in situations where nothing is visible to the naked eye.

In a report from Nikkei, Canon says that it has developed a new type of light-receiving element called a single photon avalanche diode (SPAD) and is implementing it on a CMOS sensor. SPAD photodetector technology on its own isn’t new, and has been in use since the 1970s. However, Canon has managed to create a sensor with 3.2 million pixels, which it says is more than three times the resolution of conventional SPADs and makes it the highest-resolution sensor of its type ever made.

Windows 11 is still halving NVMe SSD write speeds

Posted by in categories: computing, electronics

Months ago, before Windows 11 even shipped, beta users were complaining that Windows 11 was slowing their random write speeds on NVMe SSD by more than half.

Now, three months later and two months after the launch of the OS, it appears the issue is persisting.

Recent CrystalDiskMark benchmarks of the Samsung 980 Pro SSD performed by PleasedPen25317 show a massive reduction in random write speeds for any partition with Windows 11 installed.

Scientists develop ‘lab on a chip’ that costs 1 cent to make

Posted by in categories: biotech/medical, electronics

Circa 2017


“Enabling early detection of diseases is one of the greatest opportunities we have for developing effective treatments,” Esfandyarpour said. “Maybe $1 in the U.S. doesn’t count that much, but somewhere in the developing world, it’s a lot of money.”

Exclusive: Lytro Reveals Immerge 2.0 Light-field Camera with Improved Quality, Faster Captures

Posted by in categories: electronics, virtual reality

Lytro’s Immerge light-field camera is meant for professional high-end VR productions. It may be a beast of a rig, but it’s capable of capturing some of the best looking volumetric video that I’ve had my eyes on yet. The company has revealed a major update to the camera, the Immerge 2.0, which, through a few smart tweaks, makes for much more efficient production and higher quality output.

Light-field specialist Lytro, which picked up a $60 million Series D investment earlier this year, is making impressive strides in its light-field capture and playback technology. The company is approaching light-field from both live-action and synthetic ends; last month Lytro announced Volume Tracer, a software which generates light-fields from pre-rendered CG content, enabling ultra-high fidelity VR imagery that retains immersive 6DOF viewing.

Ultracompact camera is the size of a salt grain

Posted by in category: electronics

U.S. researchers have developed a new imaging device just 500 μm (0.5 mm) in diameter. The system can produce crisp, full-colour images on a par with conventional compound camera lenses 500,000 times larger in volume.

Thermoelectric crystal conductivity reaches a new high

Posted by in categories: electronics, materials

Just as a voltage difference can generate electric current, a temperature difference can generate a current flow in thermoelectric materials governed by its “Peltier conductivity” ℗. Now, researchers from Japan demonstrate an unprecedented large P in a single crystal of Ta2PdSe6 that is 200 times larger than the maximum P commercially available, opening doors to new research avenues and revolutionizing modern electronics.

We know that current flows inside a metallic conductor in presence of a voltage difference across its ends. However, this is not the only way to generate current. In fact, a difference could work as well. This phenomenon, called “Seebeck effect,” laid the foundation of the field of thermoelectrics, which deals with materials producing electricity under the application of a temperature difference.

Similar to the concept of an electrical conductivity, thermoelectricity is governed by the Peltier conductivity, P, which relates the thermoelectric current to the temperature gradient. However, unlike its electrical counterpart, P is less explored and understood. For instance, is there a theoretical upper limit to how large P can be? Far from being a mere curiosity, the possibility of a large P could be a game changer for modern-day electronics.
