| 20130015351 | CLUSTERING OF MULTI-MODAL DATA - Information from multiple detectors acquiring different types of information is combined to determine one or more properties of a sample more efficiently than the properties could be determined using a single type of information from a single type of detector. In some embodiments, information is collected simultaneously from the different detectors which can greatly reduce data acquisition time. In some embodiments, information from different points on the sample are grouped based on information from one type of detector and information from the second type of detector related to these points is combined, for example, to create a single spectrum from a second detector of a region of common composition as determined by the first detector. In some embodiments, the data collection is adaptive, that is, the data is analyzed during collection to determine whether sufficient data has been collected to determine a desired property with the desired confidence. | 01-17-2013 |

| 20130254948 | Scanning Method for Scanning a Sample with a Probe - The method relates to a method of scanning a sample. Scanning a sample is typically done by scanning the sample with a probe along a multitude of parallel lines. In prior art scan methods a sample is scanned multiple times with a nominally identical scan pattern. The invention is based on the insight that the coherence between adjacent points in a direction along the scan direction is much better than the coherence of adjacent points perpendicular to the scan direction. By combining two images that are scanned perpendicular to each other, it should thus be possible to form an image making use of the improved coherence (due to shorter temporal distance) in both directions. The method thus involves scanning the sample with two scan patterns, the lines of one scan pattern preferably perpendicular to the lines of the other scan pattern. Hereby it is possible to use the temporal coherence of scan points on a line of one scan pattern to align the lines of the other scan pattern, and vice versa. | 09-26-2013 |
