| Abstract: | Using light-emitting diode (LED) array, a larger scale linear light source was designed. The energy distribution of which was analyzed. Distribution data was measured with illuminance meter. Two dimensional energy plane distribution plots was given out. Linear light source designed meets the need of completely the large screen target used to measure the flying bullet velocity. The formula that computes the energy of light source on where the receiving sensor was mounted was given. The result was verified by experiment. |
