HIGH SPEED ATOMIC FORCE MICROSCOPE DESIGN USING DVD OPTICS By Thomas Beatty Carlson, MS Applied Physics A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science at Virginia Commonwealth University. Virginia Commonwealth University, 2014 Director: Dr. Jason Reed, Assistant Professor, Physics Department We examine the design of a high speed atomic force microscope using an optical pickup from a commercially available compact disc/digital versatile disc drive. An investigation of the commercial optical pickup is done with the goal of determining how it can be used for dimensional measurements on nanometer scale. An evaluation of noise sources, imaging capabilities, and functionality is performed.
