    • Abstract
  • The origins of various holographic noises and methods for restricting noises are discussed in the paper.While making hologram,the contrast of interference fringes is supposed to be increased in order to increase the diffraction.In order to obtain optimum diffraction efficiency and whole result,the ration of reference light and object light is chosen different with objects.In consideration of external environment,the exposure time should not be too long.In a certain condition,there is an optimum exposure time.Under the observation of electronic micrograph,it is shown that the information of interference fringes will be destroyed if the resolution of the recording materials is not high enough.Finally,some related problems are discussed.
