Distance Bar Chart [6]

Figure 11:

Distance Bar Chart

This is a plot of the detected objects' distance vs the confidence value (range 0

– 255) of the current

detection (measurement). The X-axis indicates the distance in millimeters and the Y-axis indicates the

confidence value. The GUI displays up to 128 bars here (8 x 8 mode, two objects per zone).

The legend of this chart has four entries:

●

Photon Count Object - this value increases with the reflectivity of the target object surface

●

Photon Count Reference - related to the optical reference channel, not influenced by the target

object

●

Background Light - related to the (IR only) ambient light, the TMF882X sensor sees

●

Temperature - the temperature of the TMF882X sensor (on-chip SPAD sensor array

temperature)
