Case Study
Weak Fluorescence Imaging
BACKGROUND CHALLENGE The team is monitoring the blinking of quantum dots in their experiments. They do this by immobilizing a single quantum dot on the top of a glass cover slip, then monitoring its intensity ?uctuation over time. However this blinking happens on a very short time scale. A normal CCD camera is not sensitive enough to image within such a short exposure time (few ms). In addition, the speed of the CCD is not fast enough to pr
