Function Principle

This manual describes the SmartRunner Explorer 3-D with time-of-flight technology (hereinaf-
ter referred to as sensor).
The object in the field of view is illuminated by a modulated, invisible infrared light (1). The
object reflects the light (2) on the sensor through the lens. The reflected light is detected with a
spatial resolution of 640 x 480 pixels. The distance data to the object is determined inde-
pendently for each pixel by measuring the phase shift. The phase position of the brightness-
modulated light source is measured using the "continuous-wave time-of-flight procedure." Four
measurements with different phases are performed. The phase shift of the reflected light is the
equivalent of the distance "d." The result of the measuring cycle is a 3-D point cloud that con-
tains intensity data for each pixel.
Figure 2.1
An example of how the measurement results can be displayed is a 3-D point cloud in the "ViSo-
lution" application software (see chapter 6.2.1).
