Abstract
Methods of reducing the speckle noise and improving the depth resolution in optical 3-D profilometry with laser sheet are proposed in the paper.Speckle is caused by object's micro-structure,with more less-correlated random structure co-interference in the imaging field,the speckle can be depressed greatly.As proved by experiments,combined the method of appreciably sacrificing the lateral resolution and dynamic image capture,the depth resolution can be effectively improved.
