Abstract：
The practical emittance measurement of a Proton Linear Accelerator inevitably involves deformation.This paper suggests a syntactic pattern recognition method to handle the deformation problem.This approach consists of two steps.The first step is to use a use a sett of shape primitives to describe the contour of the emittance shape.The second step is to analyze the description syntactically.Syntax-Directed Translation scheme is employed to remove the deformation.
