AD-FMCLIDAR1-EBZ
Introduction
The AD-FMCLIDAR1-EBZ is a prototyping platform for LiDAR applications that can be used on FPGA development boards enabled with FMC HPC connector and JESD204B support capability. It offers developers a working-out-of-box platform that can be used for developing software and algorithms for a broad range of applications.
The full system hardware includes:
Highlevel specification
1D Non-Scanning LiDAR
Horizontal resolution 16 pixels
Data sampling upto 1GSPS on 4 separate Channels
Design is verified to comply with Class I Laser Safety
Standardised FMC connector plugs into FPGA board of choice
Out of box demo for target range measurement
Complete open source software framework
Licensable JESD204B interface framework for deterministic data delivery to host
Wrappers for Matlab, Python
LiDAR specific
API for system control & data acquisition
Platform development environment support includes Industry standard Linux Industrial I/O (IIO) Applications, MATLAB®, Simulink®, custom C/C+, Python, and C# applications
HDL reference designs and drivers to allow zero day development
Laser optics are not provided with the system but ADI has a proven demo detecting an object upto 60m range at approx. 1m x 1m. Optional optics to achieve this are provided below in the Example section.
DAQ Board
Laser Board
The laser board is mated to the AFE board for mechanical mounting on an optional tripod stand. It is then connected electrically to the DAQ board using the cable provided.
It contains 4 individual lasers with appropriate precision driver and power components for accurate firing of the lasers.
To alter the laser Field-of-View custom Fast Axis Collimator optics are available from specialist optics suppliers.

AFE Board
The AFE board contains a 16 channel APD from First Sensor and four
ADI LTC6561 Quad channel
TIA's with necessary power and timing signal chains. Custom optics can be fitted to the board using industry standard mounting adapters based on individual use cases.

System setup & evaluation
The development kit is delivered with an SD card containing the evaluation software for the supported FPGA carrier boards and a set of accessories required to put the system together and get it up and running in no time.
This is what you'll find in the development kit box:
8 x SMA cables to connect the AFE and Laser boards analog output signals to the DAQ board ADC inputs
2 x ribbon cables to connect the AFE and Laser boards digital signals to the DAQ board
12V @ 4A power supply for the Laser board and power cables

Application Development
The Lidar Prototyping Platform software framework is common across all hardware variants, developed with industry standard tools and interfaces. The necessary parameters are exposed for customers to develop their own proprietary solutions. Support is provided to cover a broad base of operating systems used across different industry areas. There is a proven ADI JESD framework available to reduce development complexity and time, and guarantees deterministic transfer of data from the APD to the host processing system.
Laser Safety
This device complies with International Standards IEC 60825-1:2014 & 2007 for a Class 1 laser product. This device also complies with 21 CFR 1040.10 and 1040.11 except for deviations pursuant to Laser Notice No. 50, dated June 24, 2007. Only use Software and Firmware updates that are specifically provided for this solution.

Additional values tested
Example
As an example to prove out the overall system functionality a demo using select optics was chosen to have the capability to detect an object of approximately 1m x 1m in size at 60m range with 50% reflective characteristic.
For the AFE Board a 1“(25.4mm) diameter lens, option from Thorlabs LA1951-B-N-BK7, was chosen (included in the box)
For the laser board a custom Fast Axis Collimator optic was selected to narrow the vertical FoV from 30°(natural dispersion of the laser) down to 1° to help achieve the 60m range. Mounting of these lenses requires a custom lens holder and also active lens alignment fitting during the manufacturing process. This was done at
FISBA, a worldwide leading supplier of customized optical components, systems and microsystems with locations across Europe and in the US.
The lasers were driven at 50KHz with a pulse width of 20ns
