Stage: PROBLEM TO BE SOLVED: To accurately identify particles of interest (for example, asbestos particles) on the basis of a plurality of intensity distributions obtained from within a beam scanning range.SOLUTION: An angle calculator 42 calculates an angle representing the orientation of a surface on the basis of an intensity distribution for each coordinate within a beam scanning range. A normalizer 48 multiplies an angle array generated by the angle calculator 42 by a numerical value corresponding to a shape of interest (for example, a needle shape or a string shape). A particle-of-interest analyzer 52 analyzes whether a candidate particle is a particle of interest on the basis of a group of normalized angles corresponding to the candidate particle.SELECTED DRAWING: Figure 1 (Grant)
