Research Abstract |
A frequency scanning type interferometric laser microscope has been developed using a pair of vertical-cavity-surface-emitting-laser-diodes capable of frequency scanning with a broad scan range. The presented system can measure both the geometric height and the deformation of the test piece simultaneously. As a result of the experiments, the profile and the thermal expansion of the metal sample with a 200 micron-cube.
