| Abstract: | This study presents development of an inexpensive
modular system based on the measurement of time of flight (ToF) of
a projectile between two parallel laser screens for
velocity measurement of small caliber projectiles and can be used for both
indoor and outdoor ranges. System design consists of a
single source (laser diode) and a single detector is used to construct two
screens. It also provides better velocity measurement
accuracy because both screens are generated from same source and have
same sensitivity. Velocity measurement accuracy of
system is better than 0.08%. A 100 MHz digital oscilloscope is used to
measure ToF, which provides 20
ns time base accuracy. |
