Three-dimensional wind measurements and modeling using a bi-static Fabry-Perot interferometer system in Brazil
… east, south, and west followed by a zenith and laser image. In common volume mode, the two FPIs are synchronized to observe three common locations followed by both a zenith and laser observation. Two common volume points, one to the north and one to the south, are where the two FPIs have the …

A Multiple Sensors Approach to Wood Defect Detection
… imaging modalities: a color imaging system, a laser range profiling system and an X-ray imaging system. The objective of in designing this vision system is to detect and identify: 1) surface features such as knots, splits, stains; 2) geometry features such as wane, thin board; and 3) internal …

Optical control of polariton condensation and dipolaritons in coupled quantum wells
… are presented thereafter, including holographic laser shaping with a spatial light modulator (SLM), which allows exciting the microcavity with arbitrarily shaped pump geometries. Experimental results comprise optical control of polariton condensates, and dipolaritons. First, optical blueshift …

Development of a Novel Planar Mie Scattering Method for Measurement of Spray Characteristics
The work herein details an optical droplet measurement system based on planar multi-angle Mie scattering. Sizing information consists of a mean droplet diameter and droplet distribution estimates for every individual point within a planar (2D) area of interest. The planar method makes possible the …
