Embodiment 1

[0058] This embodiment proposes a marine plankton luminescence measurement and identification device, such as figure 1 As shown, it includes an integrating sphere 11 , a water inlet pipe 12 , a water outlet pipe 13 , a flow meter 14 , a processing module (not shown in the figure) and a light collection component. The interior of the integrating sphere 11 has a spherical inner cavity 110 , the integrating sphere 11 has a water inlet and a water outlet communicating with the inner cavity 110 , and the wall of the inner cavity 110 is coated with a diffuse reflection layer.

[0059] The inner surface of the water inlet pipe 12 is coated with a light-absorbing layer. The water inlet pipe 12 has at least one curved portion, which is the first curved portion 121. The water inlet pipe 12 is fixedly connected with the integrating sphere 11 and communicated with the water inlet. The inner surface of the water outlet pipe 13 Coated with a light-absorbing layer, the water outlet pipe 13 h...

Abstract

The invention discloses a marine plankton luminescence measurement and identification device, belonging to the technical field of spectral measurement of marine luminous organisms, comprising: an integrating sphere; a water outlet pipe, the inner surface of which is coated with a light absorbing layer, the water outlet pipe has at least one curved part; a flow meter; a disturbance device; a processing module; Photomultiplier tube array; the processing module calculates the bioluminescence kinetic hyperspectral curve in the water body according to the electrical signal sent by the photomultiplier tube array, and calculates the bioluminescence intensity, and matches and identifies the luminescent organisms. The marine plankton luminescence measurement and identification device effectively improves the bioluminescence detection accuracy and reliability by effectively shielding external natural light interference and using a gain adjustable photomultiplier tube.

Description

technical field [0001] The invention belongs to the technical field of spectral component measurement and analysis, and in particular relates to a marine plankton luminescence measurement and identification device. Background technique [0002] There are about 700 species of light-emitting organisms in the ocean, belonging to 16 phyla, ranging in size from single cells to large vertebrates, such as bacteria, dinoflagellates, radiolarians, ctenophores, cnidaria, crustaceans, etc. The photons of these light-emitting organisms span at least nine orders of magnitude, and there are obvious differences in the light-emitting time of different light-emitting organisms. Marine plankton luminescence occupies an important position in marine bioluminescence due to its wide variety and wide distribution. Plankton luminescence under mechanical stimulation has important research significance and practical application value for marine ecology and underwater target detection. In terms of m...
