With　the　development　of　science　and　technology,　many　areas　become　more　and　more　urgent　need　for　microsystems　,　thus　the　micro-mechanical　technology　which　is　famous　for　its　small　shapes　and　sizes　is　becoming　a　high-tech　by　which　people　can　understand　and　transform　the　objective　world　from　the　micro　perspective.　Micro　stereovision　via　SLM　is　applied　to　the　3D　shape　reconstruction　of　microstructures.　The　model　development　for　micro　vision　via　SLM　is　discussed,　and　a　vision　model　that　describes　the　projection　between　2D　image　space　and　3D　object　space　is　derived.　A　pair　of　optical　paths　of　SLM　is　denoted　by　a　group　of　basic　points　and　basic　planes,　and　then　two　models　of　micro　stereovision　with　SLM　are　derived　via　the　geometrical　projection　of　virtual　incident　rays　and　the　weak　nonlinear　phenomenon.　At　last,　experiments　are　given　for　3D　shape　reconstruction　of　microstructures　in　this　model.　In　this　paper,　we　introduced　a　new　reconstruction　method　-Stripes　projection　supporting.　Under　the　support　of　stripes　projection,　we　can　find　more　accurate　matching　point,　so　we　can　get　more　accurate　reconstruction.　©2009　IEEE.
