Cameras Could Take Night Photos Without a Flash





A team of scientists led by Andras Kis at the École Polytechnique Fédérale de Lausanne in Switzerland have found a material that could make cameras five times more sensitive to light, reducing or even eliminating the need for a flash or a long exposure. The material — made from a mix of molybdenum and sulfur — was used to make a single-pixel prototype sensor that only needed 1/25th of a second to expose a nighttime streetscape that other cameras would require 1/5th of a second. The sensitivity of the new sensor is fast enough that moving people didn’t get blurred.

It works because molybdenite is much more sensitive to light than silicon, the other material other digital sensors in cameras are made from.

Besides sensitivity, there’s another plus to molybdenite: it’s cheap. Unlike other exotic technologies or semiconducting materials, there’s lots of it around and factories making image sensors out of it won’t need re-tooling.

  1. It is the best time to make some plans for the long run
    and it's time to be happy. I've read this put up and if I could I desire to recommend you some attention-grabbing issues or
    suggestions. Perhaps you could write next articles relating to this article.
    I wish to read more issues about it!

  2. This design is spectacular! You most certainly know how to keep a reader entertained.
    Between your wit and your videos, I was almost moved to start my own
    blog (well, almost...HaHa!) Great job. I really loved what you
    had to say, and more than that, how you presented it. Too cool!
