title: [Application of stereoscopy on edible birds nest identification].
abstract: OBJECTIVE
  To study the feasibility of using stereoscopy in identification on Edible Bird's Nest (EBN).
  
  
  METHODS
  Characteristics of white EBN pieces, red EBN, white fungus pieces and EBN painted with colloid were observed under stereoscopy.
  
  
  RESULTS
  EBN pieces could be distinguished from white fungus pieces under stereoscope. The former is semitransparent and has more fine cracks; the latter is opaque and without fine cracks. EBN painted with colloid can be distinguished under stereoscopy too. The characteristics include: (1) the surface lines were not clear; (2) feathers were plastered on the surface.
  
  
  CONCLUSIONS
  Stereoscopy can be used in identification of EBN, especially in general investigation of commercials.
