What Do You Need to Have a Successful & Robust LIDAR System?

The GPX2 Time-to-Digital Converter is the Economical Answer

LIDAR is being used in a variety of applications today; from autonomous vehicles like drones, cars, and trucks to even collision avoidance systems. The LIDAR system needs to be robust and operate in hostile environmental conditions like temperature extremes and also deal with the variety of weather conditions likely to be encountered while traveling and still provide accurate information for the vehicle to operate. The laser, optics, and photodiode detectors are all important components to a good LIDAR system, but the accuracy and resolution of the measurements heavily depend on the component measuring the time of flight from when the laser fires to when the return occurs.

Why is the GPX2 the best solution for LIDAR systems? This device can provide resolution to 10 ps, which equates to 1.5mm resolution and a maximum measurement range that is greater than any LIDAR system today. So there is little to no risk of exceeding the maximum measurement range. The GPX2 is fast too, reaching a maximum data throughput of 70 MSPS per input channel. The GPX2 is designed to easily integrate into a system that is controlled by a microcontroller or FPGA offering LVDS inputs and outputs for highest performance. This very economical part helps to keep the overall cost of the system down and its ease of use means that development cycles are shorter.
