Abstract: PURPOSE:To scan an inclined sample face and obtain a distortionless image by providing a correction signal generator, an adder of a scanning signal and a correction signal, and a means to set the preset coefficient of the correction signal with the addition output for the (x) direction and the (y) direction. CONSTITUTION:An x-axis scanning signal generator 1x generates a linear sawtooth wave, an x-axis correction signal generator 2x generates a correction signal expressed by k(theta-a)<3>b, both of them are added 3x and amplified 4x and fed to an x-direction deflecting coil 5x. The signal proportional to the corrected y-direction signal is set as the x-direction correction signal (k). Coefficients (a) and (b) are set by potentiometers A and B. The deflection angle thetais proportional to the scanning signal. An error of d=Ltantheta-Ltheta is generated on a scanning face F. The correction quantity for it is (d)costheta/(L/costheta)= cos<2>(tan-theta), theta is small, the equation is expanded and the fourth order or above is omitted, then epsilon=1/3xtheta<3> is obtained. When the distortion is corrected in the scanning range phi for the deflection angle theta by properly selecting the coefficients (a) and (b), an almost distortionless image can be formed on a sample face in case of the scanning in the wide range where the inclination is not negligible.
