Photo-coupled data acquisition system and method

摘要

The photo-coupled data acquisition system can have a container having a contour wall extending upwardly from a closed bottom, for containing a sample therein, a light emitter operable to emit diffused light into the container at an initial intensity, a photodetector operable to detect a reflected intensity of the diffused light, and a structure connected to the contour wall and holding the light emitter and the photodetector at a predetermined height above the bottom of the container and in an orientation facing inside the container, wherein during operation of the system, the initial light intensity is attenuated by the sample and the reflected intensity thereof can be correlated to an information value concerning a variable of interest of the sample.

主权项

1. A method of obtaining an information value concerning a variable of interest of a sample having marine organisms in a water medium, the method comprising:
exposing the sample having marine organisms in a water medium to a diffused light having an initial intensity, the sample thereby attenuating the light; obtaining at least one attenuated intensity value corresponding to an attenuated intensity of the light the sample having marine organisms in a water medium; using the at least one attenuated intensity value to obtain the information having marine organisms in a water medium.
