Generally, the applications can be grouped into one-dimensional or two-dimensional measuring tasks. For one-dimensional applications, the measured result is extracted from the pixel information of an individual line scan. Measurements of two-dimensional images require moving either the object or the line sensor
- Signal generation: individual line scan
- Examples: measurement of width, rod diameter, edge positions, glass thickness.
- Several line scans are combined to produce a 2D image (frame)
- Examples: surface inspection, endless webbing inspection, texture analysis, scanning
