In tissue, the Brownian motion of endogenous light scattering particles causes scatter locations and optical path lengths to dynamically change, resulting in time-dependent intensity modulations of the laser speckle. This MPS model is a practicable method of calculating the optical fields arising in the scattering from particle aggregates and is straightforwardly extensible to arbitrary illumination and to more complex internal-particle structures, such as stratified spheres. Vital applications of this model include the exact computation of forces exerted on irregular objects in optical traps and the simulation of light propagation through biological tissues. "An obvious technical challenge in putting together this experimental proposal was the ability to numerically simulate the entire experiment using the computational resources available to us," Lewis-Swan tells Phys.org. Leveraged HDRI, and it was followed by other image-based techniques that switched to HDRI to produce a photorealistic look much more efficiently than traditional, physically based rendering methods, which require complicated computation to simulate lighting behavior. Examples of particle distributions. The scattered atoms populate a spherical …more. Oct 21, 2010 - Therefore, in image-based lighting, the pixels of the background plate act as if they were the light sources scattered in the background scene, thereby accurately approximating the lighting from the environment. Sep 12, 2011 - These diagnostic techniques measure one or more of the processes that occur when the light interacts with the tissue including the reflectance, refraction, scattering, or absorption and re-emission of the incident light (Figure 1). 1 day ago - This massive-particle version of the HOM effect uses pair-correlated atoms produced in a collision of two Bose–Einstein condensates and subjected to two laser-induced so-called Bragg pulses. The team has Groups such as Pavel Zemánek's at the Institute of Scientific Instruments of the Academy of Sciences in the Czech Republic have irradiated objects symmetrically off-axis so that they scatter light forward, giving them recoil momentum directed back toward the light sources. Aug 13, 2013 - Researchers in Florida and Singapore have produced a method of dragging objects on the surfaces of fluids that they believe could lead to new techniques for micromanipulation.
