“…The polarization state of light would change when scattered from target surface, which can be formulated by the polarization bidirectional reflection distribution function (pBRDF) [20]. This function could characterize the polarization state of both specular component and diffuse component of scattered light for a wide variety of materials.…”

In order to recognize different materials from passive polarimetric measurements specifically, a model that can describe the distribution of polarization energy scattered from the target surface is needed for estimating the parameters of interest (complex refractive index n, k and surface roughness ) of targets. This paper presents a new method for targets parameters estimation. The presented method modifies the degree of linear polarization (DOLP) model by introducing the Lorentz-Drude dispersion constants which do not vary with wavelength as well as the diffuse component of reflection related to the surface roughness to the DOLP equation. This solves the problem of difficulty and inaccuracy caused by multi-angle passive polarimetric measurements used by previous works and helps to improving the parameters estimation accuracy for rough targets. The Monte Carlo simulations result illustrate that the presented method is robust to Gaussian noise. Moreover, the experimental results of rough aluminium plate and rough copper plate validate the effectiveness of the presented model. The errors of estimated n are about 8% for aluminium plate and 9% for copper plate. The errors of estimated k are less than 4% for aluminium plate and no more than 5% for copper plate. The errors of estimated surface roughness  are about 6.8% and about 6% for aluminium plate and copper plate respectively. The high estimation accuracy and less detection angle requirement achieved by the presented method are significant for material characterization in passive remote sensing application.

Optical wireless communications (OWC) has emerged as a strong candidate for wireless communications, due to the capacity limitation in the radio frequency (RF) spectrum. Especially visible light communication (VLC) has great potential for short-range outdoor vehicular communications, as vehicle LED lights also transmit data. However, outdoor VLC channels vary fast and, experience multipath scattering and reflection resulting in time domain dispersion. Outdoor VLC links are also subjected to high levels of ambient noise, especially from the sun. Orthogonal frequency-division multiplexing (OFDM), which has proven robustness to multi path fading and noise effects in RF links can also be deployed in VLC links. In this paper, optical OFDM (O-OFDM) along with adaptive modulation scheme is investigated in VLC for vehicle to vehicle (V2V) communications. A (2 × 2) multiple input multiple output (MIMO) channel, with multiple polarimetric bidirectional reflections and realistic sunlight interference is considered. Two schemes of O-OFDM; direct current biased optical OFDM (DCO-OFDM) and asymmetrically clipped optical OFDM (ACO-OFDM) are investigated. Simulation results of the proposed model show increase in data rates up to 50 Mbps along with reduced bit error rate (BER) under both line of sight (LOS) and non-LOS and high noise conditions.
