| Abstract: | We desinged and developed an element,which can split a single laser beam produced by a He Ne laser device of 4mV power into ten paralleled laser beams with an equal space distance of 5mm between each beam pair.We've developed a photo electric transformer,which is of high sensitivity,waveform synthesised and has a single output channel.When combined with the digital oscilloscope and personal computer,we have the system can be used to measure the impacting velocity of the projectile launched by a gas gun. |
