A new lidar scheme using a pseudorandom code modulated cw laser as a transmitting laser source (RM-CW lidar) is proposed and a demonstration of its use for aerosol measurement is shown. A formula for estimating the SNR values in RM-CW lidar was derived, and it was demonstrated that the observed SNR value was in good agreement with the calculation.read more

Complex photonics: Dynamics and applications of delay-coupled semiconductors lasers
TL;DR: In this paper, a review of the properties of single and two delay-coupled laser systems is presented, with a particular emphasis on emerging complex behavior, deterministic chaos, synchronization phenomena, and application of these properties that range from encrypted communication and fast random bit sequence generators to bioinspired information processing.

Chaotic lidar
Fan-Yi Lin,Jia-Ming Liu +1 more
TL;DR: In this paper, a chaotic lidar (CLIDAR) system that utilizes a chaotic laser as the light source is proposed and studied, where the detection and ranging are realized by correlating the signal waveform reflected back from the target with a delayed reference waveform.

Resolving range ambiguity in a photon counting depth imager operating at kilometer distances
TL;DR: This work demonstrates the application of a pseudo-random pattern matching technique to a scanning rangefinder system using GHz base clock rates, permitting the acquisition of unambiguous, three-dimensional images at average pulse rates equivalent to >10 MHz.
