Free Space Ranging Utilizing Chaotic Light

Free Space Ranging Utilizing Chaotic Light

We report our recent works on free space ranging with chaotic light. Using a laser diode with optical feedback as chaotic source, a prototype of chaotic lidar has been developed and it can achieve a range-independent resolution of 18 cm and measurable distance of 130 m at least. And its antijamming...
