A New Probe with Diffraction Based Displacement Sensing

Not Accessible

Your library or personal account may give you access

Abstract

A new contacting probe is presented to measure the topography of samples in micro/nano scale. The displacement of the probe is monitored by a photodetector, which receives a diffracted beam from the probe. Analysis results of the probe, which are based on the scalar diffraction theory, are discussed.
