Monitoring crystal dissolution at nanometer resolution using laser reflectometry

Laser reflectometry has been used for the first time as an in situ real-time monitor of the dissolution of the (0 0 1) face of KClO3 crystals into aqueous solution. During the dissolution process the reflected light was subject to constructive and destructive interference caused by the movement of crystal boundaries. This produced Fabry–Perot oscillations similar to the widely exploited phenomenon used in the laser reflectometry-based metrology...
