No flash? No worries! New camera sensor eliminates the need for a flash
We’ve all been there. Times when you wanted to click a group picture but the background is too dark. Shouldn’t really be a problem if your phone has a flash, but oh wait, that gives terrible results most of the times. Scientists may have come up with a solution to that.
What if a scientist developed a new type of camera sensor which eliminates the need for an assisting flash? A team of researchers at Nanyang Technological University (NTU) in Singapore have developed a new type of camera sensor which is highly sensitive to both visible spectrum and IR (infrared) light as well. This new sensor can effectively be used for your everyday family photos as well as in surveillance and satellite cameras (drum roll).
While the inner workings are beyond our scope, we’ll try to tell you what’s most relevant. The new sensor is 1,000 times more sensitive to lighter than the average camera sensor found in today’s consumer products. This high level of photo-response is achieved thanks to its unique graphene-based structure. The inventor, Wang Qijie excitedly said:
“We have shown that it is now possible to create cheap, sensitive and flexible sensors from graphene alone,” said Wang. “We expect our innovation will have a great impact not only on the consumer imaging industry, but also in satellite imaging and communication industries, as well as the mid-infrared applications.”
Perhaps the sweetest part of this new technology is that it can be built using the current manufacturing processes, the only change required would be switching the base material to graphene. Wang believes that industry adoption of his new technology would lead to cheaper and lighter cameras, not to mention better low-light photography and ultimately, lower prices.
