Question:

What is true about the world’s fastest film camera?

  1. Capable of taking 5 trillion images per second
  2. Capturing a single image every 0.2 trillionths of a second
  3. Capable of visualising the movement of light
  4. Capturing a single image every 0.2 trillionths of a second
  5. All of the above

Correct Answer: E

Explanation:

World’s fastest film camera can ‘capture’ light. As per Einstein’s theory, nothing can travel faster than the speed of light in a vacuum that makes it difficult to capture. Now researchers at Lund University in Sweden have built the world’s fastest film camera that is capable of taking five trillion images per second. This means an image every 0.2 trillionths of a second. In other words, the camera is fast enough to visualize the movement of light or capture molecular processes. The camera could be used to observe extremely rapid natural processes and reactions in chemistry, physics, biology and biomedicine that until now have not been captured on film. The researchers exposed an object to be filmed to brief flashes of laser light, which were reflected by the object. The new technology called Frequency Recognition Algorithm for Multiple Exposures (FRAME) is based on an innovative algorithm. It instead captures several coded images in one picture and later sorts them into a video sequence. This method took four separate images per frame instead of taking images one by one in a sequence, like other high-speed cameras.
