Optical plankton: an optical oceanic probing scheme

Journal of Applied Remote Sensing, 2007
In this paper, we evaluate the possibility of a wireless sensor network concept operating in the oceanic environment. A population of underwater sensor nodes, termed "optical plankton," form a distributed sensor network characterized by the deployment of many miniature and low-cost sensors capable of profiling the particulate composition in the ...

Nanosecond gated optical sensors for ocean optic applications

Proceedings of the 2006 IEEE Sensors Applications Symposium, 2006., 2006
Nanosecond gated photosensitive modules with wide dynamic range has been design for ocean optic applications (1) on base R7400U Hamamatsu (5mm. active area) photomultiplier tube. The photomultiplier tubes R7400U series have two kinds of photocathode: low resistance semitransparent multialkali photocathodes that can be gated with nanosecond response and

Raman scattering and in-water ocean optical properties

Applied Optics, 1990
Inelastic (transpectral) scattering may contribute significantly to the in-waterlightfield. Major mechanisms for inelastic scattering include Raman scattering, which we show is important in clear ocean waters, and fluorescence from a variety of sources, which may be important in more turbid waters.

Isotropic spherical source analysis for ocean optics

Applied Optics, 2000
Plane-to-point transformations are used to develop a version of the Hydrolight computer program with which to compute the spatial dependence of the irradiance and the scalar irradiance of the light field away from an isotropic point source deep within a spatially uniform ocean.

The Ocean Optics Story in a Nutshell

2009
In this chapter the path to success followed by Ocean Optics is presented. Comments concerning the things to do first, on the business plan, on sales and marketing, on the key elements to the sales platform, on the role of trade shows and conventions, are addressed.

Optical imaging of ocean plankton

Digital Holography and Three-Dimensional Imaging, 2008
Plankton are the primary form of life in the ocean and constitute the base of the marine food web. New digital optical sampling methods from video to holography are providing new insights in plankton ecology.

Oceanic Applications Of Fiber Optics

OCEANS 91 Proceedings, 2005
Abstract : Oceanic applications of fiber optics are rapidly advancing, following on the heels of the more mature land-based telecommunication systems. While many features of each arena are similar, undersea fiber systems demand unique capabilities. Components capable of withstanding brutal hydrostatic pressures and near freezing temperatures had to be ...

Ocean-Optical Measurements Using Acousto-Optic Filtering

SPIE Proceedings, 1986
Spectral radiometric, scattering, and absorption measurements have classically been accomplished using grating spectrometers or fixed passband optical filters. Recently, holographic optical elements and linear-geometry detectors have gained popularity in spectrometric instrumentation, thereby eliminating the need for movable mechanical components ...

The Optical Information Transmission in the Ocean

1994
Ocean optics is generally considered as a branch of oceanography, but in recent years is also as a branch of the modern optics. Because of recent development of laser, optical electronics, computer and information processing, satellite remote sensing and their wide application in ocean science and exploitation, many new problems in ocean optics have ...
