Abstract:
A new method of displacement measurement that uses the transient photoelectromotive force effects that arise in semiconductors illuminated by two frequency-modulated lasers is proposed and demonstrated experimentally. A height resolution of 0.85 microm was achieved experimentally; theoretical analysis charts the path toward eventual improvement of this resolution.
