Abstract
A high-throughput optofluidic device for detecting fluorescent droplets is disclosed. The device uses time-domain encoded optofluidics to detect a high rate of droplets passing through parallel microfluidic channels. A light source modulated with a minimally correlating maximum length sequences is used to illuminate the droplets as they pass through the microfluidic device. By correlating the resulting signal with the expected pattern, each pattern formed by passing droplets can be resolved to identify individual droplets.

1-20. (canceled)
A device comprising:
- a light source configured to illuminate a plurality of droplets passing through a microfluidic channel;
- a controller configured to flash the light source in a time-domain modulated sequence;
- and
- a photo sensor configured to capture an image of the microfluidic channel.
