Local raster scanning is an algorithm for using the data acquired by an atomic force microscope in real time to steer the tip so that it stays on a sample of interest. The algorithm is suitable for all samples that are "string-like" in nature and has been shown through simulation and experiment to produce an order-of-magnitude improvement in imaging rate. This paper presents experiment results of applying the algorithm to gratings, demonstrating this improvement in speed. We compare the results
