Inversion methods for laser parameter extraction with phenomenological model based on off-axis sensor measurements

摘要

There are a wide range of applications involving laser propagation through a scattering medium. Very often, a measurement of the scattered light will be taken with the intent of learning some information about the medium. On the contrary, the present work seeks to extract a description of the source of light and its location. A phenomenological model for off-axis intensity is presented which employs a Mie scattering aerosol database. The model is extended to predict the off-axis polarized light described by the Stokes vector. Several inversion techniques are given and analysed as well as example problems are detailed which can recover the range, direction, power and polarization of the laser source.
