Reads or sets the area of the sensor used for laser detection. ZDetectionHeight is the height, in mm, of the first detection range stating at ZDetectionBase. A smaller ZDetectionHeight increases the maximum line rate when acquiring range images, but reduces the measurement range. When converting ZDetectionHeight to discrete sensor rows, the range may be expanded slightly to match the sensor capabilities. The range will only be reduced if it extends off the end of the sensor. This function can be used to ignore reflections and other artifacts that are outside the expected range of heights.
