Cj. Hughes et Jc. Earnshaw, HIGH-FREQUENCY CAPILLARY WAVES - A LIGHT-SCATTERING SPECTROMETER, Review of scientific instruments, 64(10), 1993, pp. 2789-2795
Modifications to a light scattering apparatus to permit study of liqui
d surface fluctuations of significantly higher wave number than hither
to are described. Various problems associated with the modified system
are discussed. Typical results are presented for capillary wave propa
gation on the surface of two different fluids, demonstrating the satis
factory functioning of the spectrometer despite these problems.
