    • Abstract
  • The experimental study of the influence of laser spatial coherence on illumination uniformity is made.It is shown that the coherence property of laser affects the illumination uniformity.The scintillation index and the power spectral density of the illumination spot on the target decrease with decreasing spatial coherence of laser beams.As a result,the illumination uniformity can be improved.The experimental results obtained in this paper are useful for appropriately choosing the laser illuminator in practice.
