Miniature Lidar using Diode Lasers Modulated with PN Codes

Abstract

Takeuchi et al. [1,2] first reported aerosol lidar measurements using an AlGaAs laser modulated with a pseudo-noise (PN) code in 1986. Recently, we have reported the design, theory and measurements [3-5] made with our breadboard PN aerosol lidar, which uses a photon counting detector and histogram-correlate receiver processor.
