4.4. Measurement Rate
The LeddarVu module acquires a base input waveform for each segment at a rate
between 10 kHz and 40 kHz, depending on the sensor field of view (see Table 11).
Multiple acquisitions are used to perform accumulations and oversampling, and
generate a final waveform that is then processed to detect the presence of objects
and measure their position.
Table 11: Base Acquisition Rate Based on the Field of View
Leddar Vu8 FOV
Base Acquisition Rate

10 kHz
48°
20 kHz
100°
40 kHz
Therefore, the final measurement rate is:
Measurement rate = base rate/number of segments
enabled/accumulations/oversampling
For example, Leddar Vu8 20° with 256 accumulations and an oversampling value of
8:
Measurement rate = 10000 / 256 / 8 / 8= 0.61 Hz
Table 12 presents the measurement rate for typical values of accumulations and
oversampling.
