Wide-scattering-spectrum multi-dimensional ocean profile information laser detection device

Abstract

The invention provides a wide-scattering-spectrum multi-dimensional ocean profile information laser detection device which comprises a pulse laser emission system used for continuously emitting two beams of pulse laser with different spectrum bands to irradiate the ocean; the main optical receiving assembly is used for collecting scattered signals generated by interaction of the bispectral laser and seawater and converging the scattered signals to the light splitting and filtering assembly; the light splitting and filtering assembly is used for splitting the collected bispectral laser scattering signal into two beams of light signals, and the two beams of light signals are respectively emitted into the first photoelectric detector and the preceding-stage relay optical assembly; the front-stage relay optical assembly is used for separating the incident light beam into one beam of elastic scattered light signals and two beams of inelastic scattered light signals, the two beams of inelastic scattered light signals are respectively emitted into a second photoelectric detector and a third photoelectric detector, and the elastic scattered light signals are emitted into the rear-stage relay optical assembly; and the rear-stage relay optical assembly is used for separating the incident elastic scattered light signal into four beams which are respectively emitted into the four photoelectric detectors.

Description

technical field

[0001] The invention belongs to the technical field of ocean optical remote sensing, in particular to a wide scattering spectrum multi-dimensional ocean section information laser detection device. Background technique

[0002] Ocean observation is the basic means of understanding the ocean and the basis for marine economic development, environmental protection and rights protection. At present, ocean observations have changed from ship inspections, mooring and buoy observations to satellite remote sensing observations. my country’s ocean observations started late. Although the observation capabilities have been greatly improved in the past two decades, the observation data of my country’s coastal waters and the global ocean surface are comparatively small. However, there is a lack of subsea profile data on a global scale, there are problems such as the inversion of remote sensing data is not precise, and the knowledge of information extraction is not scientifi...
