Project Description Heading link
Spraying Systems, Co. uses high speed imaging techniques to identify spray processes in their products. A device capable of high luminosity is needed for the company in order to better identify and study the high speed motion of miniscule particles, ejected through a nozzle or similar device. It is for this reason that we are trying to create an LED lighting system that can emit as much light as possible, to be captured by a camera, in a short window of time by means of overdriving an LED. Our circuit will be capable of creating short micropulses, in the 10 to 20ns range, in order to push the LED to its maximum luminosity, while using parts that are much more inexpensive than the average similar technology. We are working in conjunction with a team of Mechanical Engineers in order to assure our circuit is as efficient as it needs to be in regards to the thermal aspects of our final product, through the use of a heat sink. The circuit itself is small enough to fit in one hand and uses minimal parts in order to make it as cheap, and efficient, as possible.
