What is the application of cross-hole dipole array?
Layout the electrode as figure below:
The left red line is AM, the right red line is BN.
It’s like two same array (AM and BM), and will get too section.
Firstly, Keep the location of AB, move rightward point by point, and get a rolling line.
After complete the last point of this rolling line, move A,B,M,N rightwards at the same time, by one electrode spacing, and do the measurement just like the first rolling line.
At last, you can get two section as:
