Problems solved by technology

[0002] At present, the measurement technology of water body scattering function is relatively scarce, which is mainly due to the difficulty in measuring the volume scattering function, the special directionality of water body scattering, the large dynamic range of scattered light signals in different directions, and the weak light scattering signals at certain angles. Measurements are particularly susceptible to interference from external stray light

Abstract

The invention relates to the technical field of radiometric calibration for volume scattering function profilers and particularly relates to a continuous-light-source-based radiometric calibration system for a volume scattering function profiler. The system comprises a frequency-controllable pulsed light output control device, and a continuous light source and a radiation probe which are disposed at two sides of the control device. Light emitted by the continuous light source is modulated through the control device into pulsed light, the pulsed light is output, and the pulsed light is received by the radiation probe and used for radiometric calibration. The system is simple in structure and suitable for calibrating the radiation probe only receiving the pulsed light under a condition that only the continuous light source exists.

Description

technical field [0001] The invention relates to the technical field of radiation calibration of a volume scattering function profiler, and more particularly relates to a radiation calibration system of a volume scattering function profiler based on a continuous light source. Background technique [0002] At present, the measurement technology of water body scattering function is relatively scarce, which is mainly due to the difficulty in measuring the volume scattering function, the special directionality of water body scattering, the large dynamic range of scattered light signals in different directions, and the weak light scattering signals at certain angles. Measurements are particularly susceptible to interference from external stray light. Practical research has found that the method of light source modulation and receiver demodulation can effectively avoid the interference of background light on scattered light signals. Therefore, how to calibrate the scattered light r...
