The Use of LEDs (Light-Emitting Diode) to Simulate Weak Yag-Laser Beams

摘要

The purpose of this report is to determine whether and under what conditions a light-emitting diode may be used to simulate a weak YAG-laser beam that has been scattered by a distant reflecting object. By examining the differences between laser radiation and LED radiation, the author concludes that there is no theoretical reason that a LED may not be used in place of the laser beam.
