Free Space Ranging Utilizing Chaotic Light

الملخص EN

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 signal in noisy environment and suppress the side-lobe noise of the correlation trace.
