Figure 1: General elements of the LeddarVu module
Receiver assembly
The receiver assembly contains the photodetector array (8 elements), the circuit receiver, and a
processor (MCU).
The module generates a full waveform per segment at its measurement rate.
NOTE: Lens coating color for 47.5° configuration may change from one sample to another from
greenish to bluish, but the inherent properties of the lens are not affected in the field of
application of this product.
Emitter assembly
The emitter assembly includes the emitter (LED, VSCEL, or laser), the emitter driver circuit, and
the temperature sensor.
Light source pulsing is controlled by the receiver assembly since the receiver data acquisition must
be synchronized with the light source pulses. The temperature sensor, located near the light
source, is used to implement temperature compensation on the ranging results.
Power connection
The power connection is a 2-pin connector that provides the module with a 12 V power source.
