The development of reflectance difference (RD/RA) spectroscopy as a powerful optical probe for characterizing surfaces and interfaces has suggested that an extension to microscopic scale (micro-RD) could further increase the potential of the technique. In their article on pp. 1119–1123, Lastras-Martínez et al. compare and discuss the performance of two setups used to measure micro-RD. One is based on a charge-coupled device as light detector and the other on a laser and XY-stage. The performance of both setups was tested by measuring the micro-RD spectra of an n-type GaSb (001) sample, which was slightly rubbed with a diamond abrasive compound along either [110] or [1-10] directions. The cover shows micro-RD spectra (right image, open circles) across the surface of GaSb (001) after the generation of directional strains along [1-10]. Top left, a surface strain map obtained from fitting the amplitudes is shown, and the lower-left image presents a result using the laser-based set-up.
