System and method for measuring the area and dimensions of apertures in an opaque medium |
摘要 |
A system for measuring the average area of apertures in an opaque member scans a large number of lines across the apertures in orthogonal directions. The width of two apertures are measured to obtain an average width. The lengths of two apertures are measured to obtain an average length. The average width and length are multiplied to obtain an average area. The width and length measurements are not necessarily from the same two apertures within the member.
