[0004]
With the increase of ocean observation depth, such a design scheme has a large volume and high power consumption. When carrying out deep-water measurement with a tugboat, the pressure on the measurement equipment will increase rapidly, which will increase the difficulty and cost of structural design. The power consumption, communication difficulty and power supply difficulty will also increase accordingly, which puts forward higher requirements for the miniaturization and low power consumption of the measuring device

Description
technical field [0001] The invention belongs to the technical field of optical instruments, and in particular relates to a multi-channel combined miniaturized seawater absorption characteristic measuring device and an installation structure. Background technique [0002] In marine scientific research, in order to achieve fine observation, the absorption characteristics of seawater at different depths are one of the characteristics that need to be studied. In order to realize the measurement of seawater absorption characteristics at different depths, towing chains of a certain height are often mounted on tugboats, and seawater absorption characteristic measuring devices are installed on the towing chains at a certain distance. Measurement of absorption properties of seawater. The seawater absorption characteristic measurement device measures the seawater with a specific optical path through light sources of multiple typical wavelength bands, so as to obtain the absorption ch...
