As the conventional atomic force microscopy (AFM) uses a Cartesian coordinate system to scan sample and the probe has different characteristics in each direction, it is impossible to scan in arbitrary direction. Therefore, we present the AFM which is able to rotate its probe. The deflection of cantilever was measured using optical pickup head of DVD drive. For verifying the system feasibility, the multidirectional scanning of the standard sample was carried out. Also we presented the modified structure which includes aligner and mirror to enhance the performance.
