Depth of Field

The depth of field or 'depth of focus' refers to the range of distances over which a focused image is obtained. As with a normal camera our products are focused for a particular range. Objects outside this range will result in blurred images and inaccurate range data. Therefore the 3D Digital software automatically discards range data for objects outside the design range. This ensures that the output data is all within our specified accuracy. The following figure illustrates the concept of depth of field.
