A simple apparatus dedicated to the calibration of a low-order double-crystal birefringent wave plate is presented. These wave plates are widely used in optical instrumentation and the residual errors associated with these devices can be very importa

This paper deals with an error analysis together with the calibration of a spectroscopic Mueller polarimeter with dual rotating retarders; both of them take into consideration the elliptical birefringence characteristics of each rotating device. In d

Up to now, no technique was available to perform inventories and surveys of immersed macroalgae. This article presents a method making it possible to discriminate between macroalgae and seafloor and to identify the various macroalgae groups (green, b

This article presents measurement results of the liquid refraction index achieved with a new kind of instrument called a `capillary-cube'. This instrument is made with a glass cube bored along its whole length and lit by a laser beam. The boring diam

We have experimentally assessed the efficiency of a new underwater-target detection scheme, called modulated lidar. The technique used is based on a remarkable physical property of the propagating medium; sea-water has a low-pass transfer function in

The temporal frequency response of water supplemented with scattering particles was deduced from the measurement of the optical backscattering of a short (100 ps) blue-green (532 nm) optical pulse given by a frequency-doubled Nd:YAG laser. Indeed, th

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

Although the method based on the Mueller matrix for the experimental determination of optical-device polarization behaviour is a powerful tool, it has rarely been applied to optical fibre. This paper introduces an experimental methodology for measuri

The possibility of correctly detecting immersed targets with a lidar through the air-water interface is discussed in this paper. The water surface roughness, in relation with wind direction, greatly disturbs light dispersion. Nevertheless, a detectio

The possibility of characterizing immersed targets in laboratory conditions, whatever the water surface roughness is discussed in this paper. The first idea was to reduce the interface effects or better to suppress them within the analysis.We used th
