Problems solved by technology

The disadvantage of this method is that the absorption coefficient and scattering coefficient required for its calculation need to be obtained by other means instead of the measured value, which will cause a large error in the final result
Patent 201410026241 proposes a turbidimeter with good long-term stability by reducing the number of sealing parts. This device uses optical windows to guide the transmitted and scattered light to their respective storage spaces for measurement, but the measured scattered light is only limited to the light source. vertical direction

Abstract

The invention belongs to the technical field of optical radiation measurement and particularly relates to a multichannel liquid transmitting and scattering measuring device and method. The device is formed by arranging N single-channel cylinders in parallel; each single-channel cylinder includes an upper scattering light integration chamber and a lower transmitting light measurement chamber, the two chambers are isolated by an opaque partition and are measured by detectors respectively for the intensities of scattering light and transmitting light; all detectors are connected with external storage module and data processing module to provide remote transmission for measurement data, and transmitting and scattering rates of light of different wavelengths in a water body are measured through multiple channels at the same time; after laser of different wavelengths in each channel enter the cylinders of the measuring device, transmittance intensity of the laser is measured by the transmitting light measurement chamber and scattering intensity of the laser is measured by the scattering light measurement chamber, and therefore, the transmitting and scattering rates of the light of different wavelengths in a water body can be measured through multiple channels at the same time.

Description

technical field [0001] The invention belongs to the technical field of optical radiation measurement, and in particular relates to a multi-channel liquid transmission and scattering measurement device and method. Background technique [0002] The absorption and scattering of light by water causes serious attenuation of light in water. At present, the research on light transmission in seawater mainly adopts the attenuation coefficient model, and the attenuation coefficient of seawater is obtained through actual measurement. However, according to the difference in light transmission distance, if the required error is smaller, then the experimentally measured attenuation coefficient values ​​at different depths will be more. Although this method is more accurate, it is very inconvenient. [0003] Patent 201210041509 proposes a method of obtaining the absorption coefficient and scattering coefficient in layers to calculate the transmittance, and then multiplying the transmittan...
