| Abstract: | Multiaperture connection in Cartesian coordinates is difficult to be used to test suface of 3 D
object or rotating object. To solve the problem, multiaperture connection in Cartesian
coordinates is extended into cylindrical coordinates. Formulas in cylindrical coordinates are
given. Results of computer simulation show that the theoretical error is about 10 -7 mm,
which proves the method is correct. Testing results for a real cylinder are given. |
