Independent software for image processing, data analysis and presentation. Your Message. Main features of the Brisk. Reduced Dimensions Brisk occupies least possible space in your laboratory and its nice looking view atrracts the users. High Magnification OM The initial imaging for choosing the scan point is performed using a powerful colored OM fixed on the machine.
User Friendly Simplifications in operation together with reducing the required time for nano-imaging has made Brisk extremely user friendly. Fast Approach. New generation of the controllers. Employing the latest advanced electronics in Brisk has improved the controller functioning. Developed tip fixing procedure. You can calmly fix the tip in AFM-head in the shortest possible time. Nano imaging in least possible time duration. To use these commands, select the command, click on the files to be operated on, then execute the command.
The File menu contains subcommands that copy, delete, move, and rename files. It also includes the Real-time subcommand that tags a file to be displayed in the Real-time operating mode. The Dual subcommand in the Display Monitor menu bar allows two images to be displayed in the dual image format. The Multi subcommand displays up to six images togetlier on the Display Monitor. The Auto subcommand initiates the Auto Program mode to automatically analyze images.
The Auto Program mode is discussed in more detail in Chapter 4. Copy - Duplicates the selected file and results in two identical data files. An identical file with a new name can be created in the current directory or the copy can be created in a new directory or partition with the same name or a new name.
Delete - Eliminates the selected file. Move - Transfers the selected file to a new filename, directory, or partition. Only one file results from this operation. Rename - Changes the name of a single file. Directory - Allows a new directory to be selected. Dir Make - Creates a directory for storing files. Dir Delete - Eliminates the specified directory including any files and sub- directories contained in the directory.
Delete All - Eliminates all of the files in the selected directory. Rename All - Renames all of the files in the selected directory. The files will be differentiated by a three-digit numerical suffix appended to the new file name.
Diskette Change - Updates the file list after a new floppy diskette has been placed in either of the floppy drives. The commands under the View menu display the selected image in one of four formats available on the NanoScope. A dialog box containing several display parameters is shown on the Control Monitor for each display format. Top View - Displays the selected image from a top down perspective. The X and Y information is in the plane of the monitor and the height information is represented by the color at a given point.
Different color tables can be selected or created depending on the user preference. Typically, lighter colors represent higher data points while darker shades represent lower points on the sample. Line Plot - Displays the selected image as a series of sections in an oblique view. This format is useful for printing in black and white.
Surface Plot - Displays the selected image from a user-definable vantage point with either color-coded height information, an illuminated perspective, or a combination of both. Quick Surface Plot - Displays the selected image with color-coded height information with a choice of two oblique perspectives. Parameter - Allows any combination of the original scan parameters to be displayed in the parameter list with the image. The commands in the Analyze menu provide several means to gauge the surface properties of the sample.
Section - Produces cross-sectional views of the image along any desired line. Cursors are available to accurately determine spacing, height variations, and roughness statistics along the selected line. The Fourier transform along the line is also presented with the section view. Bearing - Calculates and displays the bearing-ratio curve and surface-height histograms for selected lines or areas on images. The bearing-ratio curve is the integral of the surface-height histogram. It represents the percentage of points above a reference plane as a function of the depth of that plane below the highest point.
Roughness - Calculates roughness parameters including the maximum Z change, the mean of the height, and the standard deviation within areas defined by the user. Autocovariance - Calculates the autocovariance function of the image and shows it on the Display Monitor. The autocovariance function is calculated by taking the inverse Fourier transform of the product of the FFT of the image and the complex conjugate of the FFr. Grain Size - Defines grain boundaries based on the height and slope of the data.
A histogram which reflects the grain-size distribution is produced. The mean and standard deviation of the grain sizes are calculated and displayed.
Fractal - Calculates the fractal dimension, a measure of the roughness of the surface, for the image. Spectral Density - Calculates and display the power spectrum of an image. The items in the Modify menu process the images to enhance features or eliminate noise in the image. Modify commands produce processed images. Resize - Converts images collected with one number of data points, the Number of samples parameter, to another number of data points.
Images captured in the x or x format can be reduced to smaller formats, while images captured in the smaller x or x formats can be expanded through interpolation to larger formats. Invert - Flips the image data along the Z axis, effectively reversing the height data. Low regions will be displayed as high regions and vice versa. Zoom - Expands selected areas of a captured image to fill the display screen. Selected features of captured images can be examined at higher magnification with the Zoom command.
Median - Replaces each data point in the image with the median value of either a 3 x 3 or 5 x 5 cell of surrounding points. The data point forms the center of the cell and is included in the calculation. The operation removes spot noise and can be applied repeatedly. Lowpass - Replaces each data point in the image with the weighted average of the 3 x 3 cell of points surrounding and including the point.
This command is faster than Fourier filtering and can be applied to the same image a number of times. Highpass - Replaces each data point in the image with a weighted difference between the data point and each of its eight neighbors.
This operation is useful in highlighting edges or areas with rapidly changing height in images. Flatten Auto - Reduces the effects of image bow and vibration in the Y direction by calculating a polynomial of selectable order Oth - 3rd for each scan line and subtracting it from the scan line.
