Super-Resolution Atomic Force Photoacoustic Microscope using Thermoelastic expansion

摘要

An ultra-high resolution photoacoustic atom microscope apparatus using thermoelastic expansion according to the present invention comprises: a first laser for generating a first laser beam; A second laser for generating a second laser beam; A laser beam delivery unit for irradiating the first laser beam onto a predetermined area of an object located at a target object; A tip abutting a surface of the object; A cantilever which is coupled to the tip and reflects and emits the second laser beam; And a photodetector for detecting a second laser beam reflected by the cantilever.;
