Folded Jamin interferometer: a stable instrument for refractive-index measurements.
A novel two-beam interferometer for the measurement of a refractive index or its induced changes is described. This interferometer consists of only two optical elements and is largely insensitive to their movement. A laboratory prototype has been built. It uses a polarized version of the folded Jamin interferometer to allow for convenient phase adjustment.
