A real time velocity measurement system for small flyers using multiple detectors

World has seen many casualties in bomb explosions from enemies and the terrorists; and defense services across the globe are working on more effective explosives. To develop techniques for analyzing the effectiveness and impact of explosives for attack as well as for defense strategies have become a necessity. Velocity measurement of bomb fragments after explosion is one such technique. However high accuracy results with minimal human interaction at ground zero is required. We propose a technique for monitoring the velocity of small flyers in real time with the help of Laser diodes and Photo detectors. We propose to have two laser source and photodiode optical screen combinations for collecting the flyer passing instances. The collected data will be processed at local level in a low cost Raspberry Pi and uploaded on web for real time access and analysis using web services.
