Sounds good, but still no color ....
Monochrome is the nature of the low-light beast.
Not gonna throw away my Nikon D4 just yet...
If this is manufacturable, I can see lots of applications. Imagine taking sports photos of a football catch with a phone, not a 2000$ camera with an $8,000 lens to gather enough light. Or, a 3” telescope taking images without a clock drive that would have taken a 100” telescope a half-hour to develop.
“Sounds good, but still no color ....”
CCD and CMOS sensors don’t detect colors, either. It’s done with on chip/off-chip filters. I don’t see why this won’t work the same way.
Maybe this will get us closer!
Yep, this should be a huge boon for astronomers and cosmologists; any telescope will suddenly be a 1,000 times more powerful.
Me thinks they are referring to the duration you can integrate the signal before reading it - which by itself is very useful.
*This is for "non-coherent" systems. Every application mentioned in the article supports this. Nothing in the article indicates otherwise.
And all for the price of a teeny tiny instantly rechargable battery about the size of a sugar snap pea ~ made out of junk.
I think I see where this is headed ~
Just occurred to me this will make invisibility cloaks quite affordable.
There is no color information when you are converting photons to electrons, right?
Add loss of freedom to your list. The intrusiveness of government placed night vision cameras will invade society beyond anyone’s dreams. Americans are already accepting a government that can destroy organizations through taxation, environment agencies that raid lawful businesses, spying on the press, targeting auditing to close business and silence critics, etc... What a scary world we live in. I do not welcome technology that can destroy privacy put in the hands a of a government intent on crushing freedom.
thanks to a new image sensor invented at Nanyang Technological University (NTU).
Nanyang Technological University (NTU)is located in Singapore, They will probably share the invention with the ChiComs.
it also uses 10 times less energy
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Is this to say that it creates energy?
Well duh! How else would our military be able to buy them?
Depends on what you mean by "convert." Photons have subjective color information from their capture scenario. Whether that information gets converted into the resulting electron stream data is up to the conversion process.
Well that will end the Night UFO flights!
As moper people have HD cams on them 24/7 the Alines shifted thier flights to night.
Now they have to stop altogether!
Even the Chupacabara and Big Foot wil also have to make adjustments to their patterns.
Let's keep it simple. The typical photodetector will release an electron whenever a photon of sufficient energy (>= "work function") bangs into it, knocking out an electron. The energy of the photon is directly proportional to its frequency = color. Therefore, to discriminate color with these type of detectors you put an optical color filter in front of each pixel that passes either Red, Green, or Blue. By knowing which detector pixel had which filter color, you can recreate the original image in RGB, which is how the human eye works. So while the color LOOKS very good there is actually a tremendous loss of spectral information occurring.
Moreover, most color cameras use a filter made up of tiles of filters, each tile having a square sub-grid of 2 Green pixels, 1 Red pixel, and 1 Blue pixel. Soooooo - the color also comes at the expense of reducing image resolution by 4.
huh?
