Leddar™One Architecture
The following diagram presents the architecture of the module.
Figure 2: Working Diagram
The Leddar™One module includes the photodetector, LEDs, MCU, the controller for LED pulsing
and data acquisition. Data acquisition is performed at a sampling frequency of 72131 Hz
(44 MHz/610).
The Leddar™One module processes the acquired data and produces measurements at a
configurable measurement rate. The measurements provide the distance of detected objects in
the conic beam.
Note:
The sensor measurement rate varies according to the oversampling and accumulation
settings.
LED pulsing and receiver data acquisition timing is controlled by the FPGA. A temperature sensor
located near the LEDs is used to implement temperature compensation on the ranging results.
The MCU recovers the waveforms from the FPGA, performs full waveform analysis, and
generates detection and ranging data. The data can be acquired and displayed in software
through the serial port.
