Test your radar detector or laser jammer with this traffic enforcement LIDAR gun simulator

Step 6 Conclusion

With this project I was able to determine how effective my old LP904 laser jammer is at detecting all these LIDAR guns.  It could detect all LIDAR guns except Laser Atlanta in stealth mode, Jenoptik Laveg, and Jenoptik LaserPatrol.  The last two guns are non-USA so that doesn't surprise me at all.

If you purchase a photodiode or phototransistor that operates close to 904nM and count the number of pulses and measure the time between the pulses you could make your own LIDAR detector using an arduino.  That might be a cool project to add on next.
