Clear Photos in Dim Light: New Sensor a Thousand Times More Sensitive Than Current Camera Sensors

"Cameras fitted with a new revolutionary sensor will soon be able to take clear and sharp photos in dim conditions, thanks to a new image sensor invented at Nanyang Technological University (NTU)."

1,000 times more sensitive? 1,024 is 10 bits, so that's 10 stops more sensitive. Hmmmmm.

Would be great if it's true, but..........

I wonder how it works at lower sensitivty, i.e would the lowest sensitivity setting be 10 stops higher?

That's more than interesting. I hadn't realised that (if this is true) current sensor technology is so inefficient.

I'm not sure what this might mean for us though. Higher sensitivity might imply higher ISO and/or higher resolution from smaller photo sites, I'm not sure it implies higher DR unless the charge storage capacity for each photosite can also be increased in proportion - in theory I think it might even go down.

The only comment I could find regarding actual images rather than the technology was "the stronger the electric signals generated, the clearer and sharper the photos". That indicates to me the most likely perceived benefit is cleaner images as the signal will be stronger compared to the noise floor.

The ability to reduce sensor cost was made at some length though and would be welcomed.

We'll just have to see, but I'll drop the link elsewhere where a couple of real sensor engineers used to hang out and see if they bite

I have no doubt that it is true. Graphene is a material defined by superlatives and it will revolutionise the technology of pretty much everything. After years of trying to isolate graphene some scientists finally achieved it with cutting edge, state of the art technology of a pencil and a roll of sellotape. In fact my daughter at the age of three achieved the same feat as those scientists but never received the Nobel prize as she neglected to publish her discovery.

Rumours are though that commercial applications will take almost as long as the Pentax full frame.

Ah, so about another four months then?!

More here ..... only 10 tiems more sensitive than Current CCD apparently ( Boo hiss ), but I suppose it depends on what you term as more sensitive in terms of stops.

10 times would equal just over 3 stops in binary. Still pretty cool

I would imagine it depends upon it's headroom.

There he is, pictured, holding a sheet of graphene, which is only one atom thick, and it is not bending. A miracle! It would bend in his hands.

With a name like Wang it's probably not the only thing bending in his hand!
