In Cartesian coordinate system, a flat can be expressed as the sum of even-odd, odd-even, even-even and oddodd functions. In the traditional three-flat even and odd function method, odd-odd function is difficult to obtain. In our paper the odd-odd function can be solved by use the Dove prism which can rotate the optical axis. The odd-odd function can calculate exactly. The even-odd, odd-even, even-even can be solved by rotating the flat 180°like the traditional method. Only five configurations are used to test the flats. The theoretical derivation and analysis are presented.
