| Abstract: | In order to achieve the optical design of underwater irradiance measurement in the ocean environment, based on the theory of ocean radiation transfer, the downward and upward irradiance of the ocean environment were estimated, and the optical design of the ocean environment irradiance measurement module was completed.The measurement ability and attitude error correction ability were simulated and analyzed, and actual sea measurements were carried out.Analysis shows that the factors affecting measurement capability include the photosensitive surface area of the detector and the angle of the transmission window relative to the detector.Attitude measurement errors include roll measurement errors and pitch measurement errors.Roll errors can be eliminated using dynamic horizontal methods and data processing methods, while pitch measurement errors can be eliminated using a symmetrically arranged dual irradiance probe measurement mode.The optical design of underwater irradiance measurement in marine environmental light field provides technical support for underwater measurement of target environmental optical characteristics. |
