The invention discloses a portable contourgraph and a contour scanning microscope and system. The contourgraph comprises a triaxial piezoelectric ceramic scanning tube which is composed of X-direction, Y-direction and Z-direction piezoelectric ceramic drivers. Each piezoelectric ceramic driver comprises a flexible amplification mechanism and piezoelectric ceramics. The flexible amplification mechanism is provided with a fixed end and a moving end and is set in a way that the moving end is enabled to produce linear displacement for amplifying the deformation of the piezoelectric ceramics. The X-direction, Y-direction and Z-direction piezoelectric ceramic drivers and a capacitance differential sensor are connected in series in turn, and the X-direction, Y-direction and Z-direction piezoelectric ceramic drivers are arranged on the position enabling the corresponding moving ends to produce linear displacement along the X, Y and Z directions. The capacitance differential sensor comprises atarget member, a probe and two sensing members. The probe is fixedly connected with the target member along the Z direction. Each of the two sensing members and the target member form a unipolar capacitor. The contourgraph has the advantages of small size, low cost and high resolution.
