Free Space Ranging Utilizing Chaotic Light

Abstract: 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 performance is presented experimentally and numerically. Finally, we, respectively, employ the wavelet denoising method and the correlation average discrete-component elimination algorithm to detect the chaotic sign… Show more

“…Despite these unique features, the correlation-based lidars with modulated CW waveforms typically have relatively low signal-to-noise ratios (SNRs) especially when the output power is limited by eye-safe regulations (average power less than 10 mW at 1550 nm) [20]- [23]. Although it is possible to increase the SNR by increasing the accumulation time window of detection, the detection throughput will be limited making them not suitable for real-time high-speed 3D imaging that requires fast detection with high throughput.…”
