Reverse engineering of polymeric solid models by refractive index matching

摘要: A reverse engineering technique allows the creation of 3-D CAD files from a solid model. model part to be engineered is created polymers having an index refraction matching that immersion liquid. Over liquid masking substantially opaque. The generally clear polymeric moved through immersion/masking layer interface while images cross section are acquired at layer. then used create digital models physical or compare existing with its
