2.2. Underlying Principles and LiDAR Fundamentals
Created by LeddarTech
TM
Inc., Leddar™ (light-emitting diode detection and ranging) is a unique
sensing technology based on LED illumination (infrared spectrum) and the time-of-flight of light
principle. The LED emitters illuminate the area of interest and the multi-segment sensor receiver
collects the backscattered light and measures the time taken for the light to return to the sensor.
A photodetector array is used and provides multiple detection and ranging segments. Full-
waveform analysis enables detection and distance measurement of multiple objects in each
segment as illustrated in Figure 1, provided that foreground objects do not fully obscure objects
behind them.
