Biaxial laser-based displacement transducer
Abstract
A simple laser-based instrument is described which produces output voltages proportional to displacements in orthogonal directions. This instrument and the associated experimental techniques have been used to measure biaxial displacements across 400-micron slots at various angles in sheet specimens of various widths.
