Field of View (FoV) and Field of Illumination (FoI)

The emitter and receiver elements of the laser sensor form a cone shape. The emitter field of

illumination (FoI) is 23°, and the receiver field of vision (FoV) is 55°. The LaserPING sensor will

only sense objects within the FoI, but may have reduced sensitivity when bright objects are

within the FoV. Readings may also be inaccurate when mirrored surfaces within the FoI scatter

light to other objects within the FoI or FoV.

When measuring long distances the sensor should be far enough from any surrounding floors,

walls or ceilings to ensure that they do not become an unintentional target, within the FoI. At

200 cm from the LaserPING module, the FoI is an 81.4 cm diameter disk. Elevation above a

surface can affect practical sensing range, since some surfaces will reflect rather than deflect:
