Mie scattering interferometer and its application to the study of Raman scattering from molecules at a mercury interface.
Interference fringes are observed produced by Mie scattering of laser light from a single microstructure or from a random array of microstructures supported above a reflecting surface. These fringes are the basis of a simple interferometer which can be used to measure distances from thousands of angstroms to centimeters. The interferometer is used to measure the height of liquid above a mercury surface. Raman scattering (RS) from the liquid is measured, and an upper limit of 10(3) is placed on the enhancement of RS from molecules at the interface. Enhancement of RS in a wedge between mercury and solid is examined theoretically.
