IPC: G01B21/30
Filed: 1993-10-08
Abstract: PURPOSE:To obtain a quantitatively accurate distortion-less image by correcting the nonlinearity of a piezoelectric body in the X-, Y-, and Z-directions. CONSTITUTION:A cantilever displacement detecting section 7 detects the displacement of a cantilever 8 and outputs a displace signal S1 to an A/D-converting section 3.

Namely, the section 4 performs Z-direction control so as to maintain the signal S1 at a fixed value and uses the Z-direction control data as measured data. However, the relation between the Z-direction control data and the displacement of the piezoelectric body 9 is linearly corrected and Z-direction recessing and projecting information in which a picture is formed is accurately reproduced since the section 4 is constituted so that detected Z-direction displace signals S5 can be fed back to the section 4 from a piezoelectric body displacement detecting section 12.
