1 scope

This standard specifies the requirements for the testing equipment, testing conditions, testing methods and testing report compilation of marine water color spectrometers. This standard is applicable to the laboratory testing of the measurement performance of ocean water color spectrometers, and the laboratory testing of the measurement performance of ground feature spectrometers can be referred to use.

2 Terms and definitions

The following terms and definitions established in GB/T 12763.5-2007 apply to this standard. 2.1 The process of determining the quantitative relationship between the output of the photodetector (current, voltage, etc.) and the incident absolute luminous flux. Note. Absolute radiation calibration includes spectral irradiance calibration and spectral irradiance calibration. 2.2 E(λ) The irradiance produced by light radiation within the unit wavelength interval at wavelength λ. Note. The unit of recommended spectral irradiance is expressed in μW·cm-2·nm-1. 2.3 L(λ) The radiance produced by light radiation within the unit wavelength interval at the wavelength λ. Note. It is recommended that the unit of spectral radiance is expressed in μW·cm-2·nm-1·sr-1.

3 The principle and structure of the tested instrument

3.1 Working principle The parameters measured by the ocean aqua spectrometer at the same time are. incident irradiance on the sea surface, downward irradiance profile in water, and upward irradiance profile in water And the corresponding depth parameters, according to the law of light propagation in the water and related models, calculate the radiance and normalization of the water just on the water surface Optical parameters such as water radiance, remote sensing reflectance, diffuse attenuation coefficient, etc. 3.2 Instrument structure The ocean aqua color spectrometer consists of a sea surface incident irradiance sensor, a underwater downward irradiance sensor, an underwater upward irradiance sensor and pressure Sensor composition. The structure diagram is shown in Figure 1. HY/T 125-2009
