Multiple scattering is always present in LiDAR measurements. It is one of the major causes of LiDAR signal depolarization when detecting backscattering from water clouds. For a given probing wavelength, the LiDAR signal is a function of the aerosol s

In this paper, we investigate the backscattering depolarization of linearly and circularly polarized laser sources propagating in dense water fogs. We limit our investigation to a simple case where an active LiDAR system is pointed toward a white dep

Polarimetric LiDAR can suppress backscattering by aerosols and increase detection contrast. Depolarization by the observed object can hinder those efforts. We present linear and circular depolarization ratios from 61 targets and the impact on contras

The influence of the initial polarization state of a source on the detection range of a system probing through natural dense water fog is analyzed. Information about the source is conveyed by ballistic, snake, and highly scattered photons. During pro

Impinging jets are often used in applications requiring important localized cooling. For example, this technique is commonly used to reduce blade temperatures inside gas turbines. When the jet impacts the inner surface of the leading edge of a gas tu
