Time-Resolved Optical Tomography in Preclinical Studies: Propagation of Excitation and Fluorescence Photons.

F. Nouizi[1], R. Chabrier[1], M. Torregrossa[2], and P. Poulet[1]
[1]Laboratoire d’Imagerie et de Neurosciences Cognitives, Straßbourg, France
[2]Laboratoire des Sciences de l'Image, de l'Informatique et de la Télédétection, France

We present time-resolved methods that rely on near-infrared photons to image the optical properties and distribution of fluorescent probes in small laboratory animals. The coupled diffusion equations of excitation and fluorescence photons in highly scattering tissues were solved using ... En savoir plus

Radiation Force Effect at the Dielectric Water-Air Interface

G. V. B. Lukasievicz[1], N. G. C. Astrath[2], L. C. Malacarne[2], M. L. Baesso[2], S. E. Bialkowski[3]
[1]Universidade Tecnológica Federal do Paraná, Toledo, PR, Brazil
[2]Universidade Estadual de Maringá, Maringá, PR, Brazil
[3]Utah State University, Logan, Utah, USA

The radiation force effects on the surface displacement can be calculated by solving the Navier-Stokes equation with appropriated boundary conditions. The surface deformation can be described by the radiation pressure as well as those forces due to gravity and surface tension. We used ... En savoir plus

For biocompatible prosthetics, from dental implants up to bone parts, manufacturers have to find the best way to correlate process parameters and the material properties as to meet the unique needs of individuals. Additive manufacturing techniques aim at creating complex biocompatible ... En savoir plus

Optical Cross Correlation for Similarity Detection

A. Farhat[1], W. Melis[1], R. Jenner[1], D. Wray[1]
[1]University of Greenwich, United Kingdom

Optical wave interference can perform instantaneous operations, such as: addition, subtraction, multiplication, and more complex operations like Fourier transform [1]. Being able to develop an optical computer that directly executes these operations without the need for a digital ... En savoir plus

Optical Manipulation of Microscopic Objects

R. Ozawa
Yokohama University
Japan

In recent years, optical manipulation using optical radiation pressure has been widely studied. In this study, the radiation pressure exerted on various kinds of microscopic objects with different laser beams was evaluated by COMSOL Multiphysics software. By changing beam shapes, ...

FEM Design of Interferometric FBGL Based Accelerometer for Underwater Applications

Malu Balachandran [1], R Rajesh [1], Sreehari C V [1], Khansa C A [1], K P B Moosad [1],
[1] Naval Physical and Oceanographic Laboratory, Kochi, Kerala, India

Fiber optic sensors have been designed for applications ranging from simple proximity detectors to state of the art inertial navigation systems. The optical sensing technique used in each of these applications depends primarily on the requirements. Fiber Bragg Grating Laser (FBGL) based ... En savoir plus

Investigation of the Flow Characteristics of an Aerosol Mixing Facility

S. Horender [1], K. Auderset [1], K. Vasilatou [1],
[1] METAS, Bern, Switzerland

The measurement and regulation of particulate matter to improve outside air quality advanced a lot over the last decades. This also made it necessary to develop primary standards for calibrating these measurement systems and in future the composition of relevant aerosols will be taken ... En savoir plus
