Signal Oversampling - expense of longer measurement time. Signal Oversampling is used to extract very weak signals from challenging surfaces such as those with large roughness or steep slopes. Signal Oversampling can be used in conjunction with CSI or Films measure modes and can be combined with other acquisition options such as Zip Scan, HDR, and True Color. When using oversampling and extended scan, be sure that the SureScan control is set to Off.
High Dynamic Range - Select the check box accommodate parts with a wide variation in reflectivity. This option causes the system to take sequential measurements at up to 3 discrete light levels to accommodate wide variations in part reflectivity. The two measurements are combined to maximize the amount of data and quality of the surface data produced. When the High Dynamic Range mode is checked, an HDR tab is added to the Measurement Setup panel for setting the various light levels.
True Color - Select the check box to enable the collection of a full color surface image for all data points in the topography map.
- Immediately following the metrology scan, a secondary acquisition is automatically executed to collect true color information about the surface at the point of best focus for each data point in the camera.
- Provides full color surface image for all data points in the topography map.
- To display color information in the 2D and 3D surface maps, select the True Color icon in the plot toolbar or context menu.
- Color information is stored with the .datx data file format.
