Localization of the virtual point source used in the diffusion approximation to model a collimated beam source

Autor: J Cariou, Xavier Intes, B. Le Jeune, Y. Guern, F. Pellen, J Lotrian

Publikováno v: Waves in Random Media. 9:489-499

This paper discusses the experimental validity of a frequently assumed fact: in a highly anisotropic scattering medium considered as infinite, a collimated intensity-modulated beam source can be modelled by a point-like source located on the emissive

Determination of optical properties of multiple-scattering media by using a coherent-modulated source

Autor: F. Pellen, Y. Guern, J Cariou, Xavier Intes, B. Le Jeune, J Lotrian

Publikováno v: Journal of Optics. 28:218-224

The present paper discusses the possibility of using a coherent beat-modulated source in a frequency domain approach to probe the characteristics of a highly scattering medium with low absorption. The theoretical approach is based on the diffusion ap

Semiconductor Optical Amplifiers (SOAs), key devices for future all-optical communication systems, are inherently polarisation-dependent, which is a major drawback for most networks applications. In spite of numerous studies carried out in order to d

OCT system with electro-dynamic shaker driven by a frequency-modulated waveform

Autor: B. Le Jeune, Jack Cariou, F. Pellen, Sylvain Rivet, G. Le Brun, F. Boulvert

Publikováno v: SPIE Proceedings.

We have demonstrated the possibility to use a shaker in an Optical Coherence Tomography system with a frequency-modulated driving waveform in order to avoid nonlinearities of the shaker.

Picosecond optical pulse backscattering measurement: determination of ocean water transfer function

Autor: Y. Guern, Xavier Intes, F. Pellen, J Lotrian, J Cariou

Publikováno v: IEEE Oceanic Engineering Society. OCEANS'98. Conference Proceedings (Cat. No.98CH36259).

This paper presents an experimental technique for the determination of ocean water cut-off frequency deduced from the water transfer function. This function is obtained by measuring the backscattering of a 100-ps optical pulse.
