Video Filmed At Four Trillion Frames Per Second Captures Light In A Flash
High-speed cameras capture frames on light sensors composed of semiconductors. Such cameras typically save each frame of a sequence on a separate area of the sensor. Feng Chen of Xi’an Jiaotong University in Shaanxi, China, Lidai Wang at the City University of Hong Kong and their colleagues instead expose each frame on separate but overlapping areas of the camera sensor.
