  • Surface profiler with vibration-damped horizontal reference surface
    Publication number: 20040080756
    Abstract: A beamsplitter (16) splits a source beam (14) into a sample path (17) and a reference path (19). The reflected beams recombine to form an interference signal (100). Reference surface (20) is horizontaly suspended on a loudspeaker membrane (30), and moved via a voice coil attached to the membrane (30). this arrangement isolates the reference surface (20) from external vibrations. The surface profile of the sample (18a) is analysed via the interference fringes, which are determined by computing maxima or minima in the statistical variance of digital data representing the interference signal (100). The apparatus may be used for calibrating laser ablation procedures in eye surgery.
