Abstract:
A scanning probe microscope comprising:a light source for generating a light beam:a support member;a first driving member having two ends and being expandable along a first direction defined by the direction between the ends, the one end being flexibly connected to said support member;a block fixed to the other end of said first driving member;a second driving member having two ends and being expandable along a second direction defined by the direction between the ends of said second driving member, the one end of said second driving member being attached to said block;a cantilever fixed to the other end of said second driving member, having a probe;a first mirror fixed to said block so as to reflect said light beam traveling along the first direction onto said cantilever, and to reflect a returning light beam which has been reflected by said cantilever; anda photodetector arranged at a position in the path traveled by the light beam after the light beam has been reflected by said first mirror twice.
