3D flash
3D flash is a type of LiDAR technology used by LeddarTech to provide detections in a
3D environment. The first two dimensions are the relative positions of the segments
in the frame (row/line and column). The third dimension is the distance of the
detection(s).
LeddarTech’s LiDAR technology creates optimal illumination of the field of view of a
target, which is then captured in segments by the sensor detector arrays. See section
3.1 on page 22 for more details.
Amplitude
The amplitude is expressed in counts and represents the quantity of light reflected
and captured by the sensor. This measure defines the strength of the digital signal.
Fig. 1: Saturation
Saturation occurs when an object is very close to the LiDAR or has a high reflec-
tance. The power of the received signal can be very high and saturates the analog-to-
digital converter.
Channel
Synonym of “segment.” See the definition of the word “segment.”
Crosstalk
The phenomenon by which an optical or electrical signal transmitted in one channel
creates an undesired effect in an adjacent channel. See section 0 on page 18 for
more details.
